Cu ore beneficiation cycle

During beneficiation of clay-containing copper-gold ores, the use of small quantities of Na 2 S (at natural pH) improves both copper and gold metallurgy considerably. In the presence of soluble cations (e.g. Fe, Cu), additions of small quantities of organic acid (e.g. oxalic, tartaric) improve gold

    Mineral beneficiation is a process by which valuable constituents of an ore are concentrated by means of a physical separation process. As one of the initial steps of extractive metallurgy, the main purpose is to prepare the ore prior to downstream purification processes. The most common mineral beneficiation processes include: sample preparation, comminution, size classification, and concentration
