ABSTRACT:
The invention provides a process for the preconcentration of metalliferous values contained in metal-bearing ore materials (ores and byproducts thereof) and involves subjecting the ore material to careful attrition to obtain a particle mixture of fine and coarse particles, separating the fine particles from the coarse particles by granulometry, and recovering from the thus-separated fine particles a cut having a particle size not exceeding about 50 microns and containing the metalliferous values in concentrated form.
