Reading: Mining | Geology

Mineral processing (or mineral dressing) is a specialized area in the science of metallurgy that studies the mechanical means of crushing, grinding, and washing that enable the separation (extractive metallurgy) of valuable metals or minerals from their gangue (waste material).The viability of using the Witwatersrand gold mine,,Facts, 2014). The gold mining and processing wastes contain large amounts of sulphide minerals such as pyrite, which generate acid mine drainage (AMD) (Rosner and van Schalkwyk, 2000). South Africa is currently faced with the challenges resulting from AMD and the government and mining companies are under pressure to find viable solutionsWhere’s The Harm – From Materials Extraction,,The mining of raw materials for electronic products—including silicon, aluminum, copper, lead, and gold—contributes to increased respiratory problems for workers, such as silicosis, tuberculosis, bronchitis, and lung cancer.
