Ore-hauling animals contributed economic savings and production to many of Arizonas mining towns and camps of the past. The expense of underground transportation constitutes a considerable percentage of the total mining cost in most mines, exceeding at times the expenditure of stoping (opening large underground rooms by removing ore

Use in Mining International Cyanide Management

Gold and silver typically occur at very low concentrations in ores less than 10 g/t or 0.001% (mass basis). At these concentrations the use of aqueous chemical (hydrometallurgical) extraction processes is the only economically viable method of extracting the gold and silver from the ore.
