    Reason 3 There are cyanide consuming minerals such as copper and zinc in gold ore. Some gold ores are accompanied by copper and zinc minerals, such as malachite, azurite, pyrocopper and sphalerite (especially oxidized sphalerite), etc., which have high solubility in cyanide solution. While leaching gold, they will “compete” with gold for.Phosphorite, or phosphate rock, is a kind of igneous or sedimentary rock in which a high amount of phosphate presents as fluorapatite (Ca 5 (PO 4) 3 F), or as hydroxystalline (Ca 5 (PO 4) 3 OH). In the current practice of the phosphate industry, phosphorite is usually upgraded from natural phosphate ore, and then the phosphate concentrate is input to an industrial process, named a wet process.
