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 concept of value is central to mineral economics as it is all branches of economics. In the minerals sphere particular problems are posed for a theory of value by, firstly, the non- renewability of mineral resources, secondly the substantial effort that must be made to convert a mineral into a useful product, and finally the perception of minerals, both economically and symbolically, as peculiarly national forms of wealth. Some thoughts are offered on different approaches to mineral resource valuation and on the frequently conflicting principles of exploitation to which these various approaches give rise. 相似文献

The deep ocean floor represents the latest frontier of knowledge about global mineral resources. The ocean environment poses unique problems for mineral resource development - problems of resource assessment, adaptation of mining technology, and management of resources common to all of mankind. In the first of three related articles on the mineral resources of the ocean, Mr. Odunton assesses the current state of knowledge about the nature and extent of marigenous minerals. He examines the processes of formation, the composition, and the regional distribution of ferromanganese nodules, which represent the most promising of these minerals at present. Attention is also given to the considerations involved in the location, evaluation and exploitation of nodule deposits. Future articles will review ocean mining technology and the economic and policy issues involved in the development of ocean mineral resources. 相似文献

Sustainable development involves meeting the needs of human societies while maintaining viable biological and physical Earth systems. The needs include minerals: metals, fuels, industrial and construction materials. There will continue to be considerable demand for virgin mineral resources, even if levels of recycling and efficiency of use are optimal, and rates of population growth and globalisation decrease significantly. This article aims to stimulate debate on strategic issues for minerals supply. While the world has considerable stocks of mineral resources overall, international considerations of the environmental and social aspects of sustainable development are beginning to result in limitations on where mining will be conducted and what types of deposits will be mined. Current and emerging trends favour large mines in parts of the world where mining can be conducted within acceptable limits of environmental and social impact. Finding new deposits that meet such criteria will be all the more challenging given a disturbing global decline in the rate of discovery of major economic resources over the last decade, and the decreasing land area available for exploration and mining.
To attract responsible exploration and mining, governments of mining nations will need to provide: regional-scale geo-scientific datasets as required to attract and guide future generations of exploration; resource access through multiple and sequential land use regimes, and frameworks for dealing with indigenous peoples' issues; and arrangements for consideration of mining proposals and regulation of mines that ensure responsible management of environmental and social issues.
The minerals industry will need to continue to pursue advances in technologies for exploration, mining, processing, waste management and rehabilitation, and in public reporting of environmental and social performance. 相似文献

There are a number of factors which are likely to limit the proportion of potentially recoverable resources that will actually be recovered. The most important of these concern the way minerals are distributed within the crust and trends in energy costs associated with mineral production. This article offers a pessimistic view of the prospects for mineral supplies early in the 21st century. The resource situation is even less hopeful when the possibility of extending the material living standards of the developed countries to everyone likely to be living on earth late next century is considered. 相似文献

The USSR has long been regarded as a resource-rich country with no need for external sources of non-fuel mineral resources. Increasingly, however, it is beginning to appear that such an assessment of the Soviet non-fuel mineral resource picture is overly optimistic. The Soviet mineral industry is beset by a variety of problems which complicate the extraction and utilization of needed minerals. The USSR remains a resource-rich country, but the difficulties it encounters exploiting its resources are multiplying. This article examines the Soviet aluminium, chromium, cobalt, copper, gold, iron, lead, manganese, platinum, titanium and zinc industries, and offers views of the Soviet resource future in each area. 相似文献

Concern for the supply of resources—renewable and nonrenewable—has been evident during the 1970s. All countries seek to increase the economic and social returns from the exploration, processing and distribution of minerals so as to improve the quality of life of their people. Proper resource management is imperative because of the interdependence of the mineral sector with other leading sectors of the economy and also because of the importance of minerals in the web of international economics. This paper emphasises the significance of recent international events as they affect the mineral industry and the Canadian position in the ever changing world of resource diplomacy. 相似文献

The USA is becoming increasingly dependent on key strategic metals (such as chrome, cobalt, manganese and platinum-group metals) from politically unstable regions of the world. This dependence is the result of an inconsistent and fragmented US non-fuel minerals policy. Neglect of the US minerals industry has led to a decline in US mineral production and processing capabilities. Options for a comprehensive US non-fuel minerals policy include increased domestic production; increased substitution and recycling; a domestic stockpiling programme; and diversification of, and ensured access to, foreign sources of supply. These four options are examined and recommendations are made for increased mineral surveys of public lands, a regulatory review, domestic production of strategic minerals, tax incentives, conservation, stockpiling, and a foreign policy that will ensure security of supply. 相似文献

At first ‘sustainable mining’ could be perceived as a paradox—minerals are widely held to be finite resources with rising consumption causing pressure on known resources. The true sustainability of mineral resources, however, is a much more complex picture and involves exploration, technology, economics, social and environmental issues, and advancing scientific knowledge—predicting future sustainability is therefore not a simple task. This paper presents the results from a landmark study on historical trends in Australian mining, including ore milled, ore grades, open cut versus underground mining, overburden/waste rock and economic resources. When complete data sets are compiled for specific metals, particular issues stand out with respect to sustainability—technological breakthroughs (e.g. flotation, carbon-in-pulp), new discoveries (e.g. uranium or U), price changes (e.g. Au, boom/bust cycles), social issues (e.g. strikes), etc. All of these issues are of prime importance in moving towards a semi-quantitative sustainability model of mineral resources and the mining industry. For the future, critical issues will continue to be declining ore grades (also ore quality and impurities), increased waste rock and associated liabilities, known economic resources, potential breakthrough technologies, and broader environmental constraints (e.g. carbon costs, water). For this latter area, many companies now report annually on sustainability performance—facilitating analysis of environmental sustainability with respect to production performance. By linking these two commonly disparate aspects—mining production and environmental/sustainability data—it becomes possible to better understand environmental sustainability and predict future constraints such as water requirements, greenhouse emissions, energy and reagent inputs, and the like. This paper will therefore present a range of fundamental data and issues which help towards quantifying the resource and environmental sustainability of mining—with critical implications for the mining industry and society as a whole. 相似文献

The end of the Cold War presents new challenges for the dynamics associated with mineral resources development. Broader approaches are needed to help mineral rich developing countries develop their minerals sector. These countries need to embark upon programmes of policy reform and privatization in order to make their mineral resources industries more efficient and responsive to free market forces (such as supply and demand and price), and to turn mineral sector decision making over to the private sector. This article examines the use of policy reform and privatization strategies to increase mineral resource production in developing countries, thereby contributing to both developing country economic growth and developed country access to mineral supplies . 相似文献

The USA's dependence on imported sources of strategic minerals has grown substantially since the second world war, while its ability to protect the sealanes critical to foreign supplies has deteriorated. Domestic production has been severely hampered by a lack of access to mining on public lands, and by excessive environmental regulations. No major purchases have been made for the strategic stockpile in 20 years. Concern has been growing in Western Europe and in Japan about secure supplies of strategic minerals. Being even more dependent on foreign sources of supply than the USA, some of these countries have recently initiated their own strategic stockpilling programmes. The USSR, long an important exporter of metals, appears to have changed its mineral trade policy, and has sharply reduced exports while entering the market as an importer of a number of key metals. These developments foreshadow growing competition for world supplies of strategic minerals. 相似文献

The production, price and economic resources profiles of a number of mineral commodities are examined and consideration is given to the theory that such profiles can be related to one another within the framework of a life-cycle model of development. While the behaviour of some of the commodities examined appears to lend support to the theory, that of others reveals fundamental problems with its underlying assumptions. It is concluded that, while the demand for a mineral commodity in specific uses may indeed manifest cyclical tendencies, as a general behavioural theory and as a basis for resource estimation the life-cycle model applied to minerals is of little value. 相似文献

This paper investigates the mineralogical characteristics of fresh, aged and hot water extracted MSWI fly ash for providing the baseline information of minerals stability which controls the released heavy metals into the environment. Quantitative determination of bulk phase abundance in the fresh fly ash by the XRD Rietveld refinement method provided composition levels for amorphous and crystalline phases such as potassium tetrachlorozincate (K2ZnCl4), gehlenite, halite, quartz, anhydrite, and feldspar. The minerals association in the fly ash is clearly unstable and subject to mineralogical reactions. The phases of K2ZnCl4, halite and anhydrite in the fresh fly ash were involved in hydration and dissolution/precipitation processes to form new minerals such as the Zn-bearing mineral gordaite, syngenite, gypsum and hydrocalumite. The solubility-controlling phases and extractability of heavy metals were examined in a Soxhlet hot water-extractor. Here the soluble salts were simply removed from fly ash while Ca-, Al-, Si- and SO42−-bearing hydrate minerals were precipitated from the extraction solution. Furthermore, a low release of heavy metals Zn, Pb and Cd in hot water was noticed, indicating a strong retention of the trace metals in the mineral phases remaining in the insoluble fly ash residues. 相似文献

Australia is one of the world's main producers and exporters of both fuel and non-fuel minerals. Among the main commodities produced for export are bauxite/alumina, iron ore, and nickel—Australia is also an increasingly important source of supply of black coal, especially for Japan, and is a significant producer and exporter of a number of base metals. Resources are adequate to support a substantial expansion of both non-oil fuels and other minerals. The potential for growth, both in terms of specific commodities and in the overall role of Australia in the world mineral industry, will depend to a very large extent on the cost competitiveness of Australian mining and on continuing inflow of capital. 相似文献

The feasibility of trebling production of essential non fuel minerals by AD 2000 is considered in relation to a rise in world population to 6 billion (109). Adequate supplies of common bulk ‘minerals’ like sand and gravel, brick clays and saline deposits, are assured, but mining will place additional strains on local environments. Ores of the metals that can be regarded as available in sufficient quantities include iron, aluminium, chromium, titanium, copper and nickel, and possibly also lead and zinc. In spite of the geological constraints imposed by complexity of geometry and genesis, reasoned resource estimates are possible for these, but they may not be feasible for rarer necessary minerals, such as those of the precious metals, mercury, niobium and flourine. The extraction of even the commonest of the non fuel minerals is conditioned by the availability of abundant energy at economic prices – this should be regarded as the critical factor. 相似文献

In this paper, we extend the debate on the resource curse by focusing on a new mechanism. Theoretically, resource abundance may have a negative influence on financial development by impacting trade openness, the demand for financial reforms, social capital accumulation and productive investments. Using provincial panel data of China, the empirical analysis confirms such a negative link between mineral resource abundance and financial development. The resource-rich regions tend to have a slower pace of financial development than resource-poor ones. Since the positive relationship between financial development and long-run growth is also confirmed by the analysis, our findings suggest that financial development constitutes an important mechanism through which resource abundance can impact economic performance. 相似文献

Projected increases in demand and thus increasing metal prices have brought the exploration and exploitation of marine mineral resources back into focus. The Atlantis II Deep, located in the central Red Sea between Saudi Arabia and Sudan, is one of the largest marine sulfide deposits known, with high concentrations of metals such as zinc, copper, silver and gold. However, little is known about the economic potential of marine minerals as well as the legal constraints. Our geological assessment shows that the deep is similar in grades and scale to large land-based deposits. Its economic potential is far from negligible. The total present value of possible gross revenues for the four metals zinc, copper, silver and gold ranges from 3.03 to 5.29 billion US$, depending on the assumptions made concerning future price development, mass calculation and discount rate. From a legal perspective, a general duty to cooperate in the exploration and exploitation of non-living resources located in disputed maritime areas is identified in both customary international law and in UNCLOS. It is submitted that a joint development agreement is one means of ensuring compliance with this duty in general and in the case of the Atlantis II Deep in particular. 相似文献

Two kinds of disparities pervade China and threaten its well-being. The first, regional disparities focus on levels of economic development, which vary considerably across China. The second is largely a corollary of the first, referring to mismatch in energy supply and demand, with some places suffering severe shortages while others are blessed with significant surpluses. Western China enjoys the dubious distinction of recording the country's lowest levels of economic development while, paradoxically, being blessed with plentiful reserves of energy and non-energy minerals. Turning those surplus resources to good account through transferring them to minerals and energy-hungry Eastern China is seen by policy-makers as something of a panacea. Not only will such a strategy significantly boost Western China's economic prospects, but it will eliminate the resource shortages currently constraining the East's vibrant growth. The issues of regional disparities, energy mismatches and transfers of these resources are discussed, with attention given to both spatial and time perspectives. The paper concludes with a cautious endorsement of the policy initiatives that promote the strategy of mineral transfers. 相似文献

The author reviews recent estimates of world resources and reserves and notes that reserves tend to grow with mineral consumption. Legal and economic constraints to the extraction of minerals are at least as important as physical availability. The author also points out that there is far more investment in minerals (government induced investment, companies diversifying into mining, etc) than some commentators suggest. However, the large mining projects of the 1960s belong to the past, and supplies of minerals may well become tight if there is a concerted economic boom. 相似文献
