In some plants, some of the leaching occurs in and is integral to the grinding circuit .

Sino Grinding Mineral Processing, Mineral processing typically involves the crushing and grinding of hard rock ore. Crushed ore is introduced to semi-autogenous grinding SAG mills, also known as primary mills, where grinding media is released like hammers to assist in the ore cracking / grinding process. The mix of media and ore rises and falls in the mill like clothes in a dryer.

What is Grinding in Mineral Processing? - MINERALLURGy, in minerallurgy, grinding is usually a preparatory process for the ore concentration and/or hydrometallurgical processing. There is a decrease in the size of the ore and a release of particles, opening the splices of valuable minerals to each other and related minerals. After grinding, the ore leaves with dmax = 0. -0.0 mm.
