Gangue Wikipedia

In mining, gangue is the commercially worthless material that surrounds, or is closely mixed with, a wanted mineral in an ore deposit. It is thus distinct from overburden, which is the waste rock or materials overlying an ore or mineral body that are displaced during mining without being processed, and from tailings, which is rock already stripped of valuable minerals. The separation of mineral from gangue is known as mineral processing, mineral dressing, or ore dressi

Reutilization of gangue wastes in underground backfilling

Feb 01, 2021· Gangue backfilling mining (GBM) can effectively alleviate the gangue accumulation pollution and the overburden aquifer destruction. To efficiently evaluate the reutilization of gangue wastes by GBM and its advantage in overburden aquifer protection, non-Darcy hydraulic properties and deformation behaviors of granular gangues were studied through laboratorial, theoretical, and in-situ

Mine Waste Transfer and Disposal Methods Mine Tailings

Overburden -> Gangue -> Tailings. Overburden Waste rock, or overburden, refers to the often large mass of initial soil and rock that is removed in order to get to the valuable mineral deposits in mining operations. Typically, for every ton of ore that is mined, 5 tons of overburden must be displaced.

Mining Waste Management and Disposal Methods

Aug 25, 2020· Gangue: This refers to the rock waste that is mixed in together with the valuable mineral being mined for and needs to be processed. Mineral processing is the separation of the mineral from the gangue. Overburden: Despite overburden mining not being subjected to any chemical process, it must be removed for miners to reach the ores

Research on Optimization of a Solid Filling Mining Face

Optimizing the mining scheme is an essential work for improving recovery efficiency of filling mining. An optimization equation of mining face width under a gangue mining condition is derived firstly. Then, analysis of the optimization equation of the mining face width is carried out based on the measure data of the F5001 mining face in the Tangshan Coal Mine.
