Gold processing

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).
