The nature of the ore deposit determines the mining and mineral processing techniques applied.Oxide ore depositsarefrequently 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).
