Ashes, slags and dusts by-products from mining and metal processing are sources of toxic metals, such as Pb, Cd, Hg, As, Al, as well as particulate matter. Physical, chemical Abstract Technologies for the conversion of coal mining and processing wastes into commercial products depending on the characteristics of raw materials are considered. It is shown that the production of construction materials from coal wastes can be most popular.

Vegetative Stabilization of Mineral Waste Heaps

As discussed in Section 4 these surfaces are quite varied in nature and may be either anthropogenic or natural in origin. The former category includes land devastated by strip mining, tailing heaps from mineral processing, aggregate piles for construction, and fuel ash from the combustion of pulverized coal.China, 2School of Minerals Processing and Bioengineering, Central South University Catchment area Mining sites Waste rock heaps Total number of abandoned mining adits Creek A Site A1 A1-ICharacterization and risk assessment of soil around waste mining

Heaps of waste rock covering land surfaces is estimated to require about 1 to 3 ha/Mt of solid waste. These piles may generate dust and discharge fine particles into surface waters, and they also deface the local landscape: open-pit mining operations, for instance, leave large cavities in the scenery.Mining and mineral-processing wastes—the solid and liquid materials generated after mining and ore processing at or near mine sites ()—have no current economic use.A number of environmental problems are associated with the disposal of this waste, including contamination of streams and lakes and pronounced landscape The Challenges of Reusing Mining and Mineral-Processing Wastes

Environmental and Socioeconomic Impact of Copper Slag—A

Over the years, many mining and mineral processing operations have accepted the responsibility of protecting the environment by following safe disposal regulations of the waste produced. Since the waste is of no use to the mine operations, it is disposed of on vacant land, and it has accumulated over the years into heaps/mountains Mining waste is one of the largest waste streams in the EU. It can contain large quantities of dangerous substances. Mining waste comes from extracting and processing mineral resources. It includes materials such as topsoil overburden (which are removed to gain access to mineral resources), and waste rock and tailings (after the Mining waste Environment

Figure 3 Waste rock from an open pit operation has a wide range in particle size, and significant variability from one location to the next within the stockpile.. Spent Heap leach. In heap leach mining operations, rock is placed in constructed piles on the ground surface in multiple lifts and a chemical solution is repeatedly passed through the heap to dissolve During metal processing in a smelter, a waste called slag is produced (Gorai et al., 2003). The extraction of copper in one mine generates an average of 2.3 million tons of waste per year (Çoruh et al., 2012). Similarly, in the case of zinc and lead, 1 ton of extracted metal generates 19.

Mine Waste Rock an overview ScienceDirect Topics

Coal mine waste rock (CMWR) generated in coal mining activities is one of the most significant sources of industrial solid waste. Nearly 4.5 billion tons of CMWR stockpiled in more than 1700 waste dumps occupying 150 km 2 of land worldwide ( Bian et al., 2009; Zhao et al., 2008 ). Moreover, it is expected that more than 315 million tons of CMWRChina’s total coal production in 2021 exceeded 4.13 billion tons, 52% of the world’s total. Coal gangue, a solid waste of coal mining accounts for 15–20% of coal production, when directly discharged on the ground surface as waste heaps, it occupies large areas of land and cause environmental pollution. This paper summarizes the Underground Disposal of Coal Gangue Backfill in China MDPI

Heap leaching

Gold heap leaching. Heap leaching is an industrial mining process used to extract precious metals, copper, uranium, and other compounds from ore using a series of chemical reactions that absorb specific minerals and re-separate them after their division from other earth materials. Similar to in situ mining, heap leach mining differs in that it places ore
