  • History - db0nus869y26v.cloudfront

    A refractory ore generally contains sulfide minerals, organic carbon, or both. Sulfide minerals are impermeable minerals that occlude gold particles, making it difficult for the leach solution to form a complex with the gold. Organic carbon present in gold ore may adsorb dissolved gold-cyanide complexes in much the same way as activated carbon.

    These are deposits typically found as epithermal and mesothermal veins, and rarely as strata bound deposits. The manganese minerals may form ore-grade concentrations, or may be present as gangue in association with ore minerals of other metals, commonly with Pb-Zn-Ag vein mineralization. Examples include USA, Chile and Kazakhstan.

    Hydrogen peroxide (H2O2) is a strong oxidizer that causes non-selective oxidation of sulfide minerals, and its influence on bismuth sulfide ores is not well-documented. In this study, H2O2 was proposed as an alternative bismuthinite depressant, and its effect on a Mo-Bi-containing ore was intensively investigated by batch flotation tests.

  • Effect of Gold Cyanide Leaching Is Poor? Here Is the Solution!

    Because the carbon in the gold ore is quite active, it can absorb the dissolved gold, and then precipitate again, thus reducing the rate of gold leaching. Solution: According to the carbon content of this kind of ore, two kinds of methods can be used: physical mineral processing and chemical mineral processing.
