Cost of Stoping for Underground Mining

Stoping cost is one of the largest of the items comprising the total cost of producing ore The cost per ton of ore mined is important but may be overemphasized if the more important cost that per unit of metal recovered is thereby overlooked A given stoping method may give a low cost per ton of ore but by reason of high dilution involving the handling hauling hoisting and treating of a...
