Gold Extraction Processing and Environment Consideration

2019-7-11  Extraction of gold. A common method of gold extraction is to dissolve the gold ore in an alkaline solution of cyanide. In any case, for the environmental protection of the workplace, the storage and disposal of the reagents should be seriously considered. The waste slag after gold extraction can be disposed of together with flotation tailings.

gold processing Mining and concentrating Britannica

The nature of the ore deposit determines the mining and mineral processing techniques applied. Oxide ore deposits are frequently of such low grade (e.g., 3 to 10 parts per million) that extensive mineral processing cannot economically be justified. In this case they are merely shattered by explosives and then piled into heaps for extraction by cyanidation (see below).
