redox · Sodium thiosulfate is a component of an alternative lixiviant to cyanide for extraction of gold to form a strong soluble complex ce{[Au(S2O3)2]^{3−}}. The advantage of this approach is that thiosulfate is essentially not toxic and that ore types that are refractory to gold cyanidation ( carbonaceous or Carlintype ores) can be leached by thiosulfate.
various thiosulfate gold from black sandblacksand leaching on sodium thiosulfate Jan 01, 2013· This time I crushed the black sand concentrates as best I could without a proper crusher and then I roasted them to break down the sulphides. After the cons quit smoking and stinking I plunged them into ice water to "crack" them and further release micron gold from its ...
THIOSULPHATE LEACHING – AN ALTERNATIVE TO CYANIDATION .thiosulphate leach solution onto copper metal powder, or some other reductant, following separation of solids and liquids in the leach slurry by filtration or counter current decantation. Use of the resininpulp method is limited to those deposits requiring mild thiosulphate leaching conditions, since strong thiosulphate leach conditions result

THIOSULFATE LEACHING OF SILVER FROM A SOLID RESIDUE .hydrometallurgical methods (thiosulfate atmospheric leaching) in order to recover silver and other accompanying metals. Leaching of noble metals using oxygenated sodium cyanide solutions was patented in 1887. The major benefit of this method is high selectivity of silver versus gold
Study on Gold Extraction from ThiosulfateEthylenediamine ...thiosulfate used in this test was used to examine its effect on leaching of gold The leaching conditions are as follows: the copper ion concentration is selected as /L, the ethylenediamine concentration is selected as / L, the pH value is adjusted to about 10, the
Sodium thiosulfate | Na2S2O3Sodium thiosulfate is an inorganic sodium salt composed of sodium and thiosulfate ions in a 2:1 ratio. It has a role as an antidote to cyanide poisoning, a nephroprotective agent and an antifungal drug. It contains a thiosulfate(2).
Enhancing sludge dewatering and heavy metal removal by ... · This paper studies the improvement of sludge dewaterability and heavy metal removal with sodium thiosulfate as the source of energy for Acidithiobacillus thiooxidans. Through orthogonal experiments with specific resistance to filtration (SRF) as the target index, four factors (FeSO 4 dosage, Na 2 S 2 O 3 dosage, sludge reflux ratio and sludge moisture content) were identified to be the ...
The effect of solution parameters on the thiosulfate ... · a. Effect of pH on gold recovery in thiosulfate leaching of gold. Solution parameters: mol/L sodium thiosulfate, mol/L sodium carbonate, mol/L Cu (II), mol/L sodium citrate and mol/L EDTA. b. Effect of pH on the amount of copper ion in thiosulfate leaching of gold.
Sodium thiosulfate for smallscale gold leaching from ...I recently read that sodium thiosulfate can be used for gold and silver leaching in much the same way as cyanide, but with no worries about toxicity. This intrigues me: aqua regia is a pain to work with, and cyanide is too toxic for an amateur, but thiosulfate is already one of my favorite reagents cheap, nontoxic, and has so many uses.
