Grinding Mill
It is using sand mill grinding model which is super-fine coarse discarding pre-selection process, it can achieve 30% before material into the ball mill such as iron ore. At the same time, material size is small and ore can fully dissociation, thereby greatly improving the production capacity of the ball mill.
Ore Processing Challenges in Gold Operation Grinding
Over-grinding does not have a significant benefit to gold recovery but reduces the mill throughput and results in higher unit costs in terms of energy, grinding media and reagent consumption. If there are frequent changes in ore hardness, grinding circuit performance is affected and poses challenges for operators to maintain the target particle size.

The top half of the central pillar in the South Zone has been mined, and the mining of the bottom half has begun. The west pillar was under development when CMJ toured the mine in March. "The central pillar has held up well," says mine superintendent Rick Stransky, "because it was mined strategically, with one multi-level retreating vertical face.

How it Works: Crushers, Grinding Mills and Pulverizers
Crushers, grinding mills and pulverizers are types of grinding equipment that transform or reduce a coarse material such as stone, coal, or slag into a smaller, finer material. Table Source: Wikipedia (Crushers) Cone crushers use a spinning cone that gyrates in the bowl in an eccentric motion to crush the rock between the cone surface, referred to as the mantle, and the crusher bowl liner.

Mining Basics
Part 1: Useful sources to start with As I am no geologist, mining engineer, mining company executive, etc, it seemed useful to refer to other, far more capable sources to get a solid, basic understanding of mining. The website of one of the largest gold miners, Newmont, does an excellent job in explaining the basics of the mining process, and also gives information on gold, silver and copper.
