How Metals are Mined | Cooperative Extension Service

Ore processing - separating the valuable minerals (such as gold) from the rocks - takes place in the mill facilities, usually as close as possible to the mining site to reduce hauling costs. While there are many ways to process different kinds of ore, generally the mill starts by grinding ore into a powder. This big machine, called.

The Effects of Blasting on Crushing and Grinding Efficiency and .

Large, hard rock mines expend enormous amounts of energy, with associated costs. A substantial portion of this energy is expended in crushing and grinding. Most particularly, energy consumption in grinding is large. The reason is that the change from feed size to product size, achieved in grinding, is typically much greater.
