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).
Leaching (Gold Dissolution) Once Vat is loaded with ore, is flooded with a leaching solution of a desired cyanide concentration (usually 600 to 1000 ppm) and pH between 10 to 11 at ambient operating conditions through the filter section of the floor or added to the top of the ore charge. fPicture 3: Left is the loading of tails read for ...
