Small-scale mining and cleaner production issues in Zambia

Small-scale mining (SSM) has had unprecedented growth in Zambia during the past decade. The sector now produces a variety of commodities, especially gemstones, building and industrial minerals. From a structural and technical perspective, SSM is conducted on a very rudimentary level using basic tools such as picks and shovel, and occasionally, mechanized equipment. The environmental degradation caused by SSM is also growing with the intensification of activities in the country. Meanwhile, institutions responsible for managing the environment are unable to effectively carry out regulatory and monitoring mandates due to inadequate resources. Although current legislation appears to be adequate in many respects, time has now come to amend the Mines and Minerals Act (1995) so that it becomes mandatory for all mining activities, including small-scale mines, to submit environmental impact assessment reports before a license to mine or explore can be granted. Strategies to eliminate illegal mining, enhancement of miners’ technical skills, and mine responsibly must also be placed high on the agenda. This paper focuses on the major issues affecting cleaner production in the Zambian SSM sector including, environmental complications, pertinent mining environmental legislation, and the institutions involved. It concludes by suggesting possible interventions to minimize environmental impacts in the sector.     

Indian small-scale mining with special emphasis on environmental management

Although small-scale mining provides a wealth of socioeconomic benefits to the rural inhabitants of developing countries, there is often total disregard for the environment industry-wide. This paper focuses upon some of the key environmental issues in the Indian small-scale mining industry. The geo-environmental factors constraining the mining of the Himalayan limestone, magnetite, phosphate, and polymetallic sulphur ore deposits are discussed, and the environmental impacts of small-scale operations working prospective deposits are detailed. The paper further examines the schematics of the Environmental Management Plan (EMP) adopted for small-scale mines in India. It is concluded, however, that widespread environmental improvement can only be achieved industry-wide if additional mining cooperatives are formed, and the Indian Government, through their Department of Environment, oversees the implementation of effective mitigation practices for small scale-mines, particularly at the university level.     

Climate change and mining in Canada

Climate is an important component of the operating environment for the Canadian mining sector. However, in recent years mines across Canada have been affected by significant climatic hazards, several which are regarded to be symptomatic of climate change. For the mining sector, climate change is a pressing environmental threat and a significant business risk. The extent to which the mining sector is able to mitigate its own impact and adapt to climate change will affect its long-term success and prosperity, and have profound economic consequences for host communities. This paper draws upon case studies conducted with mining operations in Canada involving in-depth interviews with mining professionals and analysis of secondary sources to characterize the vulnerability of the Canadian mining industry to climate change. Five key findings are discussed: i) mines in the case studies are affected by climate events that are indicative of climate change, with examples of negative impacts over the past decade; ii) most mine infrastructure has been designed assuming that the climate is not changing; iii) most industry stakeholders interviewed view climate change as a minor concern; iv) limited adaption planning for future climate change is underway; v) significant vulnerabilities exist in the post-operational phase of mines. This paper argues for greater collaboration among mining companies, regulators, scientists and other industry stakeholders to develop practical adaptation strategies that can be integrated into existing and new mine operations, including in the post-operational phase.     

Promoting cleaner production in the Indian small-scale mining industry

India is among the top ten mineral producing nations in the world and its economy depends on the value of minerals produced. Although mineral production has increased significantly since the country’s independence, what continues to be overlooked in is the contribution of resident small-scale mines to national mineral output. Approximately 90% of India’s mines are operating on a small-scale, employing some 0.5 million people. However, because of their rudimentary and highly migratory nature, these operations feature poor environmental management practices and safety conditions. This paper examines the unique techno-economic and socio-cultural characteristics of selected small-scale mining regions in India. It furthermore underscores the need for cleaner production in these regions, and outlines a series of legislative measures pertinent to the industry. The paper concludes by identifying educational- and training-related initiatives, which, if undertaken, could facilitate additional environmental improvement at sites.     

A project-based Mine Closure Model (MCM) for sustainable asset Life Cycle Management

Responsible Life Cycle Management (LCM) of mines has received much attention in the South African legislation. However, there is currently a mis-alignment between the mining industry and the various government authorities pertaining to the issue of mine closure or end-of-life management. The main reasons for this are unclear and unformulated approaches to rehabilitation with a subsequent legacy of unsuccessful mine closures that have wrongly been issued by the government from a sustainability perspective; this has posed an excessive economical burden for the mining industry. In this paper, a Mine Closure Model (MCM) based on project management principles, including risk management and concurrent engineering, is proposed to manage the closure process and assist the governing body with the effective evaluation of closures and the issuance of certificates. Mine closure or rehabilitation objectives can be achieved whilst managing the resources (of industry) optimally and aligning the closure process to meet the end requirements of stakeholder groups.     

Environmental management in the Brazilian non-metallic small-scale mining sector

Non-metallic mineral resources, albeit very important to meet the needs of the Brazilian population and for exportation, are ill-favored by governments and ignored by the public. Most of this mining is performed by small-scale companies and informal operations that cause extensive and widespread environmental damages. In addition to examining the current state of the industry and its environmental impacts, this paper outlines a series of initiatives for improving (environmental) performance. The suggestions made include improved coordination among public entities responsible for the control of the mining sector; the undertaking of environmental management and reclamation initiatives; research and diffusion of mining and environmental technology; the development and implementation of appropriate licensing procedures for small-scale mines; and the reviewing of environmental impact evaluation and enforcement procedures, and improved regional planning. It is concluded, however, that the proposals will only become a reality if the necessary political actions are taken, and are supported by adequate financing and technical assistance.

Mercury-free gold mining technologies: possibilities for adoption in the Guianas

The rudimentary nature of small-scale gold mining activities often generates a legacy of extensive degradation and deplorable social conditions, both during and after activities have ceased. Small-scale mining usually involves the extraction of secondary gold from placer deposits (alluvial, colluvial or elluvial), which can be liberated and treated using gravity methods. In the Guianas, the most popular form of small-scale gold mining is referred to as “land dredging”, a combination of hydraulicking and suction dredging. This method requires application of large volumes of water for both mining and mineral processing; in most cases, there are no containment structures for the waste tailings generated. Mercury, a dangerous pollutant, is the preferred method employed by small-scale miners for gold recovery. Gold extraction using mercury is comprised of the following four stages: (1) amalgamation, (2) separation of amalgamation, (3) removal of excess mercury, and (4) burning of the remaining amalgam to produce a gold sponge. Mercury can be released into the environment at each stage, which makes the promotion of mercury-free alternatives imperative.Technical alternatives for small-scale gold mining, however, must be thoroughly evaluated, pre-tested, modified accordingly and successfully transferred. Moreover, technology must be inexpensive, relatively simple and easy to adapt, while allowing a rapid rate of return. WWF-Guianas is working with the regulatory agencies and other relevant stakeholders of the Guianas to reduce the environmental footprints caused by small-scale mining. The major aspects of this program are to develop the capacity and regulatory mechanisms within the local government, to promote mercury-free technology, and monitor mercury in the environment. This paper reviews the alternative technologies being investigated by the WWF-Guianas for use in the small-scale gold mining industry.
