Grinding, i.e. reducing the particle size of mined ore, is often the bottleneck of the mining concentrating process. Thus, even small improvements may lead to large increases in profit. The goal of the grinding circuit is two-sided; to maximize the throughput of ore, and minimize the resulting particle size of the ground ore within some acceptable range. In this work we study …

Grinding wheels are thick pieces of compressed composites that quickly grind through thick metals and remove big problems, like rust or tarnish. Grinding wheels generate a lot of heat, which could cause thinner pieces of metal to warp. If a grinding wheel cracks from the heat, it could break and throw shrapnel.

The size of grinding depends on the size of the mineral being recovered. Large minerals only require a coarse grind, whereas small sized minerals require a finer grind. The slurry of crushed rock and water is placed into an agitator tank, a frothing chemical is added and a collecting chemical, usually a xanthate, is also added to the tank.
