Reduce ore dilution and loss in open pit mines

Ore loss occurs when material containing grade (ore) is incorrectly sent to a waste dump. When a cost is given for Ore Loss, it is the sale value of the metal (gold, copper) recovered from this ore (i.e. ore tonnes x grade x recovery rate x metal price). Dilution occurs when waste is unintentionally with material containing ore and sent to the Get price

Gold processing

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 Get price

The Most Important Gold Prospecting Tools

Gold

The processing of gold ore involves crushing, treatment with chemicals, melting (smelting) and further purification. It is then poured into moulds where it cools and hardens as gold bars called 'bullion', which make the gold easy to stack and transport. The first stage of processing gold ore is crushing. Get price
