Potential environmental concerns associated with mining. 2012-1-1 Reclamation of Solid Wastes Comprehensive utilization of solid waste resources is an important disposal method of solid waste from mines. Facing the problem that more and more solid waste, many mines in China begin to utilize tailings and waste rock as resources in various ways to reduce the discharge of solid waste and to protect environment. Waste management techniques employed by mining companies are routinely under intense scrutiny from local governments and the general public. Improper disposal methods and the resulting environmental damages have plagued the history of the mining industry. These actions have left a negative stigma associated with mining and associated waste Mine wastes are a broad group of waste materials resulting from the extraction of metals and non-metals. The wastes include solid, as well as liquid waste, and can be inert or can contain hazardous constituents. In general, mine waste consists of high volume, low toxicity wastes (EPA, 1985). 2018-11-8 The influence of waste disposal was determined as significant and diverse, leading to the transformation of all natural compartments surrounding waste disposal sites. The situation is especially aggravated when there are some mining and processing facilities within one relatively small territory. As a result, strong influence zones are formed. The annual disposal of iron ore tailings in Brazil is about 200 million tons, approximately 35% of the total generation of tailings in the country (IPEA, 2012). 2019-5-9 The most physically destructive aspect of iron mining stems from the mines themselves, such as open pits and waste disposal areas. Open pit mining disturbs the earth more than underground mining, which usually does not create more than .1 km of waste rock areas. Open pit mining, on the other hand, produce far more waste 2005-5-8 Both the volume of waste and concerns about waste disposal increase with a society's affluence and population density. A systems approach to mineral resources examines materials flow (Fig. 3), the fate of a resource from its original source in a mine to its ultimate destination in the waste stream. Many mineral resources that would have ended 2017-11-28 The use of abandoned mines for hazardous waste disposal has already been tested in several cases as an alternative to typical landfills. Utilization of underground mines is . believed to be an achievable, low-risk and relatively cheap solution for the disposal of hazardous waste. Underground mines, depending on the surrounding rock mass and 2011-9-2 4.1 Waste reduction measures like recycling, form the most important aspect of any waste management system. Some progress worth mentioning is ~he open-pit back-fillin~ at Nchanga and the newly-introduced underground mining technology of "cut and fi 11" in Luanshya which could significantly reduce th~ amount of wastes for disposal.
