Gold processing - Mining, Concentrating, Refining: 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 …
The technological processing flowsheet for gold-bearing ores varies widely. The choice of a particular technological flowsheet depends on several factors, including the nature of the gold in the ore, especially its size and chemical composition, the nature of the minerals associated with the gold, the presence of other valuable components in the ore, and the …
