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
