Apr 01, 1979  Huge quantities of solid wastes are generated as a result of mining and mineral processing activities in the United States. Over the years, the majority of these by-products have been disposed of in unsightly dumping areas which are aesthetically unattractive and often degrading to the environment. However, many of these wastes, because of their similarity to conventional soils and

Mine wastes management - Mining and Blasting

Mine wastes management Mining wastes is generated during the process of extraction, beneficiation and processing of minerals. Extraction is the first phase that consists of the initial removal of ore from the earth. This is normally done by the process of blasting, which results in generation of large volume of waste (soil, debris and other ...

Lecture 4: Mining waste - SGU

However, when the rocks contain certain minerals in enough quantity combined with poor management of the waste, it can become a large risk to the environment and health of local communities. Waste occurs in several stages of the mining process and throughout the life of the mine, from the first exploration drilling project to the last processed ...

The Challenges of Reusing Mining and Mineral-Processing Wastes

Mining and mineral-processing wastes are one of the world’s largest chronic waste concerns. Their reuse should be included in future sustainable development plans, but the potential impacts on a number of environmental processes are highly variable and must be thoroughly assessed. The chemical composition and geotechnical properties of the source rock determine which uses are most ...

Mining - Wikipedia

Mining is the extraction of valuable minerals or other geological materials from the Earth, usually from an ore body, lode, vein, seam, reef, or placer deposit.These deposits form a mineralized commodity that is of economic interest to the miner. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay.
