Goldprocessing -Goldprocessing -Miningand concentrating: The nature of the ore deposit determines theminingand 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 ...Get Price
