Gold processing Mining and concentrating Britannica

Gold processing Gold processing Mining and concentrating: 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

MINERAL EXPLORATION AND MINE DEVELOPMENT

Ore is the rock from which an element ultimately will be extracted. The weight percent (or grade) of the desired element in the rock varies considerably from one mineral to another at operating mines—much less than 1% by weight for gold, more than 60% by weight for some iron-ore mines. Ore usually is transformed into concentrate at the mine site.
