Manual mining method is normally limited to float ores and small mines. Mining of reef ore is also being done manually on a small scale.
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.Coal mining processing plant in Nigeria.
