  Leaching of Gold with Copper–Tartrate–Thiosulfate Solutions

  2023630 · To better understand the dissolution process of pure metal in aqueous solutions, the kinetics of gold leaching with copper–tartrate–thiosulfate solutions were carried out using a pure gold disc technique. The effects of temperature, initial pH, copper, tartrate, and thiosulfate concentrations on the gold dissolution process were examined.

  2019124 · A finely divided solids feed, F, of 150 kg/h, containing 1/3 water soluble Na and 2/3 insoluble ash is to be leached and washed at 30 C in a two-stage, countercurrent system with 400 kg/h of water. The leaching stage consists of an agitated vessel that discharges slurry into a thickener. The washing stage consists of a second thickener.

  Gold Metallurgy & Leaching in Cyanicides

  2016714 · Gold Metallurgy & Leaching in Cyanicides Cyanidation as applied to ordinary gold and silver ores is a relatively simple process. When cyanicides {cyanide-consuming elements) are encountered in small amounts in the treatment of such ores, the various schemes already discussed, such as use of a lead salt or wasting barren solution, …

  Leaching of Gold with Copper-citrate-thiosulfate Solutions

  2021819 · The addition of copper and citrate in thiosulfate solutions can accelerate gold dissolution rate by about an order of magnitude. For the copper-citrate-thiosulfate system, thiosulfate ion works as the complexing agent for aurous ion, and it is extremely critical to the gold leaching process.

  Design of a Combined Gravity Concentration and …

  2021414 · Research shows that recovery in these traditional sluices yields much losses of the gold (mostly fine gold) to tailings, resulting in low/poor recovery. Therefore, this project seeks to design a combined gravity concentration and leaching plant to improve gold recovery in the small-scale mines.
