from the dissociation of the complex is used to leach gold from the ore. The stepwise dissociation of cyanide from copper cyanide complexes can also be used to leach gold from a variety of oxide and sulphide ores. The copper cyanide's fourth ligand readily dissociates at low cyanide concentrations for use in gold leaching.
cumulative NaCN consumption by the ore after certain leaching periods, respectively, while Figure 1 demonstrates the overall leaching NaCN consumption of the ore in this test. The analysis showed that maximum Au extraction was achieved after 96 hours. At this point, Au extraction was 77.61%. For this Au recovery, approximately 1 kg/tonne ore
14/07/2016· Mispickel .6. When this mineral occursin a gold ore, a proportion of the gold is frequently in intimate association and only rendered open to cyanide attack by previous roasting. With a sweet roast, the calcine usually yields a high gold extraction with low lime and cyanide consumption.
Gold Mining Equipment Diamond Mining Equipment Dove. DOVE is the world major manufacturer of dredging equipment, gold dredging equipment and Floating Plants for river mining of gold, diamonds, gemstones, tin, etc. Gold dredges, diamond dredges, produced in various configurations suction dredge plants 5 models, with capacity range 300 1000 m3Hour slurry.
preferred method for treating low grade gold ores because of its low cost. Between 10 20% of the gold recovered each year from primary sources is extracted by this technique. The advantages of this process are: Simplicity Favorable capital Favorable operating costs, which will generally be lower than the alternatives
