Ghana is the second largest producer of gold in sub-Saharan Africa, and has experienced a significant increase in national mining production over the last two decades. Between 1983 and 1998, the mining industry brought approximately US $4 billion in foreign direct investment to Ghana. While large-scale gold mining has seen a significant increase, artisanal gold and diamond mining product have grown exponentially. While much research has been conducted on gold mining in Ghana, there is relatively little research on the environmental and human development consequences of diamond mining in the country. Unlike other West African countries such as Sierra Leonne and Liberia, small-scale diamond mining in Ghana has not been linked to conflict but its role in development has also been relatively modest. This paper examines large and small-scale mining in Ghana's largest diamond mining town, Akwatia, and their relative impact on environmental degradation, health, and the livelihood of artisanal miners. We conclude that while an increase in artisanal diamond mining has been a means of employement and income-generation for small-scale miners, there are some human development challenges, related to environmental burden from land degradation and health. GCD is an ailing mining company in Ghana, in desperate need of an injection of capital to keep the mine alive, but botched bidding has slowed the process of de-regulating the company. We also conclude that the de-regulation of GCD may lead to a relatively reduced environmental burden in Akwatia and more revenue for the GCD to invest in the human development needs of communities in the town.  相似文献

Mineral reserves are unevenly and erratically distributed throughout the world; those countries which were intensively explored in the past — the USA, Canada, the USSR, Australia, South Africa, and a limited number of Asian, African, and Latin American countries — control a large share of many of the industrially important metallic minerals. Current attitudes towards exploration and the mining industry in both the developed and the less developed countries should clearly encourage rather than discourage new exploration. Given an increase in exploration, new reserves may well be found in previously unexplored areas, but any major increase in world mineral supplies will probably come from mining very low- grade deposits and developing new methods of mining and processing non-conventional ores. While it is vital to increase research and development in exploration techniques and mining and processing technology, it is also critical to maintain current levels of consumption and trade by reversing the trend towards trade restriction on the part of some of the less developed countries who are important mineral exporters.  相似文献

This review analyses some of the environmental and economic implications of current trade policies and changes in the world trading system for mineral producers and consumers. A principal factor which determines environmental performance is whether firms have the resources and capabilities to undertake innovation. We therefore place particular emphasis on the anticipated effects of liberalized trade on innovation and competitiveness at the firm level. Evidence indicates that improvements in environmental management would be expected to occur irrespective of the country hosting the investment. Due to the opening investment climate and relatively large quantities of mineral reserves, we expect these effects to be positive for many mineral producing developing countries. One difficulty which may arise is whether policy measures to promote production efficiency and develop innovation in mining and mineral processing operations could be interpreted as protectionism. The creation of new lines of credit, to promote, but not subsidize, technological and organizational innovation, may be the best way forward for developing countries .  相似文献

Mineral production from sub-Saharan Africa is an important contributor to the economy at the country, regional and global levels. As an example, in relation to global production, the region provides 40% of diamonds, 20% of bauxite and 20% of rutile. However, with two or three notable exceptions, the region's share of mineral production has been declining compared to that of other regions. Whereas in some cases ore reserve depletion has been a factor, the most important underlying cause has been the absence of an enabling environment to attract high-risk exploration investment and to support private sector mining development. There has also been insufficient re-investment by the region's state dominated mining enterprises. Overall, growth is unlikely to occur unless an enabling environment is created to secure and maintain the appropriate levels of investment. The World Bank has recently initiated an African Mining Policy Study with the objective of recognizing and then introducing required adjustment processes into the region's mining industry.  相似文献

Mining finance experts, meeting under the auspices of the United Nations Centre for Natural Resources, Energy and Transport, agreed that sufficient capital could be provided to permit worldwide mineral demand to be satisfied, but that there was a danger that mining investment in developing countries would not keep pace with those nations' resource potential. A variety of suggestions were offered for improving the ability of developing countries to attract capital for mining.  相似文献

Remarkable changes are occurring within the economies of the USSR, China and India that are influencing mineral industry activities. These three countries account for a major share of world minerals production and consumption. Their domestic reforms may ultimately have a serious impact on the global mining industry. This paper examines the present status of the Soviet, Chinese and Indian mineral industries, and forecasts conditions to 2010. Long-term characteristics analysed include industrial production, intensity of use, consumption, mine and plant expansion and trade policy. Six metals are highlighted in the study – aluminium, copper, lead, nickel, steel and zinc.  相似文献

The US mining industry is increasingly an industry of industrial and construction minerals production. In 2002, these types of minerals accounted for 80% of the value of non-fuel minerals produced in the USA. Industrial and construction mineral production tend to be smaller operations and nearer urban areas than metallic mining and have somewhat different problems. This paper is a study of the growing impact of urbanization and land-use fragmentation on mining, particularly industrial and construction minerals production. An analysis of the state of Michigan is used as a case study to present the issues and concerns.  相似文献

This paper presents the quantitative results of recent research on Canada's minerals and metals industry, and its international competitiveness for mineral investment. The information and analysis presented are derived from the work of a Canadian government-industry task force that was created in 1991, under the auspices of the Intergovernmental Working Group on the Mineral Industry (IGWG). Much of this work deals with mining taxation in several Canadian provinces. More importantly, an attempt is made to evaluate the total tax burden that the mining industry must bear, on a project basis, at all levels from exploration through refining operations in many important competitor countries. While the focus of the paper is on an international comparison of mining taxation, some non-tax issues relating to Canada's competitiveness for mineral investment are addressed .  相似文献

The mining industry has been one of the backbones of the socialist countries of Eastern Europe, not only in economic, but also in political, terms. Three years after the beginning of economic reforms, the mining industry in all the Eastern European countries is facing dramatic changes. Most mines are mining ores below acceptable cut-off grades, and there is no hope of finding new, richer deposits. Downstream metallurgical industries will need to replace their former suppliers. In addition, the social contract that had been maintained under the socialist governments is about to be undone and a new form of internal organization must be found. The success of the economic reforms in Eastern Europe depends upon the capacity to develop new industrial relations: the large mining combinates will have to be transformed into competitive capitalist enterprises and the role of the state must be redefined. Prospects for this transformation vary greatly, from metal to metal and from country to country. Finally, restructuring in Eastern Europe will also affect European and world markets, both on the supply and demand sides. The integration of the Eastern European mining industries into the international mining community should be the medium-term goal of all the participants .  相似文献

The Australian gold industry has grown enormously over the past 25 years. Australian mine production of gold in 2003 was 284 t, similar to that of the USA, and behind South Africa, the world's largest gold-producing nation. Gold is Australia's third largest commodity export, worth an estimated A$5.3 billion in 2003–2004.Underpinning the industry is a solid resource base that has grown by successful exploration over the past three decades. Australia ranks third in the world after South Africa and the USA in terms of its economic gold resources. The growth in Australia's gold resources has been underpinned by high levels of exploration and innovations in gold processing technologies, specifically the development of carbon-based gold extraction methods that allowed commercial treatment of low grade ores. It has been supported by advances in gold exploration methods, especially exploration geochemistry.New resources were added at existing deposits and new deposits were found, including several of world class (>100 t contained gold), in each decade over the 25-year-period but resource growth since the 1990s has been dominated by brownfields additions rather than new discoveries. Average costs of discovery have now plateauxed at around A$20–25/oz, after falling sharply during the early to mid-1990s when a number of new discoveries were made, notably in the Yandal belt in Western Australia and the Lachlan Fold Belt in New South Wales. Current gold reserve/production and gold EDR/production ratios are 12 and 19 years, respectively, and indicate that the long-term future of the Australian gold industry depends on continued high levels of exploration and the discovery of new deposits to replace mines that are currently being depleted.  相似文献

Gold mining is the major economic activity in the Upper Tapajós River Basin of the Brazilian Amazon. This article studies the structure, economy and impacts of gold mining operations in this region. Mining has significant environmental impacts in this region resulting in the removal of approximately 67 million m3 of sub-soil per year and accompanied by an annual release of some 12 tons of mercury to air, ground and rivers. In the early 1990s there were 245 mines in operation, employing some 30000 people and producing around 35t gold per year, valued at approximately $400 million yr-1, the profits being about $110 million yr-1. Miners spent most of their earnings on local goods and services, while mine owners and merchants in the gold towns invested in land (mainly for ranching), business ventures and money markets. Wealth gained from mining has served as an engine for development in other regions of the world and could, theoretically, achieve the same for Amazonia. However, before this could happen, the Government of Brazil would need to mark a strong presence in the area by providing technical assistance and developing and enforcing mining/environmental regulations. The likelihood of such a development materializing in the foreseeable future is small. In the meantime, gold mining acts, not as an 'engine for development', but as a destabilizing force — provoking environmental damage, social discord and public health hazards in the region.  相似文献

This article examines possible future trends in the mining industry in the light of past developments. After a preliminary discussion, the article considers various aspects of demand, supply, corporate structures, geographic distribution of investment, and social and environmental factors influencing the minerals industry. Scepticism is expressed about the smooth, exponential growth envisaged by many commentators. Some risks are elaborated, and a digression about gold is included.
The article argues that, while the minerals industry has concentrated on reducing cash costs through technical innovation and productivity improvement, new approaches may be needed in future that are not directly linked to economies of scale. Contracting out is an interesting trend with major implications.
The view that the mineral industry's corporate structure is becoming increasingly concentrated is challenged. Developments in consumer countries as well as historical precedents strongly suggest a more diverse structure.
The spread of minerals investment from North America and Australasia, and the resurgence of foreign direct investment in minerals projects, are placed in context and discussed from the viewpoints of both companies and host countries.
Although the appropriate responses to many of these issues can only properly be made by governments at all levels, the industry has to play its part.  相似文献

Mining is an important part of the South African economy and has been the driver of much of the economic development of the country. However, the small–scale mining subsector still has to realise its full potential. A small–scale mine has been defined as a mining activity employing less than 50 people and with an annual turnover of less than 7.5 million Rand and includes artisanal mines. Small–scale miners are involved in many commodities but there appears to be a bias towards gold, diamonds and quarrying for construction materials, including brickclays. Small–scale mining is regulated by the same legislation (i.e., for the environment, labour, mineral rights, exploration and mining permitting, and skills development) as large–scale mining, though compliance is low, particularly where artisanal mining in concerned. The effective participation of small–scale miners in the mining sector is hampered by their lack of skills, i.e., technical, business and management, and their limited access to mineral deposits, capital and markets. Some of these hindrances have been inherited from the imbalances of the colonial and apartheid eras and continue to act as barriers, making entrance to the industry difficult. For those who have entered the industry out of desperation, as is the case with most artisanal miners, their activities result in negative impacts evident in the inefficient, unsafe and environmentally unfriendly operations. With the advent of the new political dispensation in South Africa, a new era is dawning for the country’s small–scale mining subsector. This has resulted in a change of attitude and new government policies which have led to special programmes being put in place to promote the subsector. Intervention strategies for the support of small–scale mining (some of which are already in operation) include programmes for kickstarting mineral beneficiation and value–addition projects, development of appropriate technologies and skills and technology transfer. Proponents of small–scale mining see a well–regulated industry as being the cornerstone of future rural economic development, particularly for previously disadvantaged communities in the poverty nodes.  相似文献

This paper provides an overview of the initiatives that have been undertaken by the Ghanaian government to promote more sustainable development in resident small-scale gold mining operations, and recommends a series of strategies for perpetuating a pattern of continued improvement. Since the passing of the Small Scale Gold Mining Law (PNDCL 218) in 1989, which effectively legalized small-scale gold mining as an industry in Ghana, the government, in particular, the Minerals Commission, has made a concerted effort to regularize operations, and to provide technical and financial support to miners. Under the auspices of the German non-profit Gesellschaft Technishe Zusannebarbeit (GTZ), a small-scale gold mining registration system has been implemented, district support centres for small miners have been constructed and the Precious Minerals Marketing Corporation (PMMC) has been created, which purchases products from small-scale miners at near-market prices. Careful analysis reveals, however, that these efforts have collectively only had a marginal impact, and that the industry is still in dire need of aid. Specifically, to perpetuate further a pattern of improved sustainability--improvements in both the socio-economic and environmental arenas--additional technical and financial support must be provided, and sound environmental management practices implemented. The Minerals Commission has been burdened with these tasks and challenges but because it is largely understaffed, it is highly unlikely that it will be able to facilitate sufficient improvement in the sector on its own. Nevertheless, marked improvements can be achieved if: (1) avenues for technological dissemination are created and improved; (2) research partnerships are forged with local universities; (3) experienced consultation is hired when needed; and (4) other governmental agencies, namely the Mines Department, Environmental Protection Agency (EPA) and Geological Survey, provide the Minerals Commission assistance with prospecting, monitoring, regulation and environmental auditing activities.  相似文献

Australia has experienced rapid development within its resource regions, with traditional mining sectors like coal, iron-ore and natural gas expanding and new industries such as coal seam gas emerging. As a result, there is an increasing prevalence and awareness of the cumulative impacts of the extractive resource industries on the society, environment and economy of these regions. Collaborative governance is emerging as a means of addressing cumulative impacts. This article undertakes an analysis of 30 case studies of collaborative governance in the resources sector of Australia. The initiatives analysed range from those focussed on information exchange and coordination to higher degrees of collaboration that involve shared resources and shared risks. The study demonstrates that there are challenges in using collaborative approaches to tackle cumulative impacts, but that significant benefits can be realised. The study highlights the need to nurture and cultivate collaborative relationships in order to provide the foundation for long-term solutions.  相似文献

This paper examines the relationship between quality of life indicators and the gross value of minerals production from Australian regions. We used quality of life indicators, aggregated for 71 local government areas containing mining activities, of household income, housing affordability, access to communication services, educational attainment, life expectancy, and unemployment. We find no evidence of systematic negative associations between quality of life and the gross value of minerals production. Instead, mining activity has a positive impact on incomes, housing affordability, communication access, education and employment across regional and remote Australia. Whilst we do not establish causality between mining activity and quality of life, our analysis prompts a rethink of the resource curse as it applies within a single country. We did not find evidence of a resource curse, at the local government level, in Australia’s mining regions. Nevertheless, we note observations by many other researchers of negative social impacts on specific demographic sectors, localities, families of fly-in fly-out mining operations, and individuals. This contrast may be a scale issue, with the regional benefits of mineral wealth masking highly localised inequalities and disadvantage. We suggest that there is a need to better understand these impacts and, more importantly, the types of policy mechanisms government and industry can adopt to mitigate or avoid them.  相似文献

The concept of sustainable development is debatable within the mining context as the fact that mineral resources are non-renewable makes mining inherently unsustainable. The need for a realistic definition of sustainability that can be applied to mining is important, in light of claims by the industry that sustainable development principles underpin aspects of their operations. Furthermore, the socio-economic upliftment that should logically follow the implementation of these principles is not visible in many mining areas. Within the theoretical frameworks of intermediate sustainability, our study aimed to determine the level of sustainability that is appropriate for the mining context. The evaluation of community perspectives within the Rustenburg platinum region in South Africa as a case study, based on qualitative information derived from structured questionnaires and informal interviews brings further clarity. We found out that the environmental and social costs associated with mining were high, while economic benefits to surrounding communities were low. The perceptions of community and corporations were found to contrast sharply: the reality experienced by community members fell well short of the optimistic scenarios presented in the corporate social responsibility reports of the mining companies, which has implications for the mining industry in the area. The Rustenburg region is typical of mining areas, more especially the developing world, and application of a realistic sustainable development concept here can help the mining industry elsewhere to move its operations onto a genuinely more sustainable path.  相似文献

Through linkage creation, commodity extraction has the capacity to support local industrial production and capabilities building. Drawing on the experience of supplying inputs into the East African gold mining industry, this paper examines the constraints experienced by local suppliers arising from the purchasing procedures of large mining corporations and specialist construction companies contracted to construct these mines. Lead firms become locked-in to particular ways of working which minimise the opportunities that local suppliers have in providing products and services. After reviewing the situation for local mining suppliers in East Africa, the paper examines ways in which lead firms, the suppliers themselves and others (governments and industry associations) can better support local supplier involvement.  相似文献

Transforming China's coal mines: A case history of the Shuangliu Mine   总被引:1,自引:0,他引:1  
China is the largest coal producer and the largest coal consuming country in the world. Approximately half of China's coal comes from small‐scale mines. The sustainability of China's coal industry would be improved if a greater share of the coal come from larger‐scale mines. This article presents a case history of the Shuangliu Mine in Shanxi Province and discusses the issues and benefits of the transformation of this mine. Significant gains were observed in worker safety and benefits, and in more efficient exploitation of the coal resource. Problems included loss of employment opportunities for local labourers, and reduced revenue for local townships. The wider implications of a shift of China's coal supply from small‐scale to large‐scale mining operations are discussed in relation to economic, social and environmental aspects.  相似文献

Energy planners in developing countries have traditionally sought to meet their nations' growing electricity demands by adding more generation and transmission capacity. But as the foreign investment situation became critical in the 1980s, private investment and system efficiency improvement programmes began to garner interest. One of the most promising system efficiency improvement options is load management, which uses a variety of techniques to utilize the electricity system's existing capacity more efficiently. However, to date, only three countries have seriously considered implementing large load management programmes: Pakistan, Peru and Costa Rica. This paper describes a 1987-89 load control demonstration programme in Costa Rica, sponsored by the US Agency for International Development (AID), in which participating industries were able to reduce their peak demand by 14%.  相似文献
