Guidance on Classification of Copper Concentrates for MHB

Copper concentrates are mainly produced by flotation. The ore is crushed and milled to a particle size of less than 100 µm. This produces a mix of particles containing pure phases of primary or secondary copper sulfides. The ground ore is mixed with water and reagents, to form a slurry, where the copper sulfide mineral particles

The next step is to feed the crushed ore into a wet grinding process in tumbling mills. These mills contain the ore, water and steel balls and further reduce the particles to the optimum size for the flotation process which follows. About 80% of copper from ore is generated using flotation, smelting and refining.

Mineral processing Wikipedia

Comminution is particle size reduction of materials. Comminution may be carried out on either dry materials or slurries. Crushing and grinding are the two primary comminution processes. Crushing is normally carried out on "run-of-mine" ore, while grinding (normally carried out after crushing) may be conducted on dry or slurried material. In
