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 ...
