METHODS OF MINING AND PROCESSING MINERAL RESOURCES

Аннотация

Minerals are solid, liquid and gaseous substances extracted from the earth's interior for human use . Solid minerals, in turn, are divided into combustible (peat, shale, coal) and non-combustible, which are: agronomic (apatite and phosphorite), non-metallic (quartz, barite, etc.) and metallic (ores of ferrous and non-ferrous metals). Beneficiation of minerals is a set of processes of mechanical processing of mineral raw materials with the purpose of extracting valuable components and removing waste rock and harmful impurities that are of no practical value in the given technical and economic conditions. As a result of beneficiation, a concentrate is obtained from the ore, the quality of which is higher than the quality of the ore.
