Process for regenerating thiosulphate from a spent thiosulphate gold leachant

摘要

A New process to regenerate from a solution of thiosulfate thiosulphate exhausted comprising the steps of: a) reacting the agoatada thiosulfate solution with Sulfur to PROducir elemental Sulfur and thiosulfate Solution regenerated; (b) separating the elemental Sulfur of thiosulfate Solution regenerated; (c) Reducing the Sulphur ebiologicamente elemeNTAL separately to produce sulfide and sulfide; (d) return to step (c)).This can be applied in a process to extract precious metals such as Gold from a suspension containing GoldBy contacting the liquid with a Solution containing thiosulphate ion and Oxygen to produce a solution of thiosulfate GoldBy contacting the solution with a Gold thiosulfate to produce an Absorbent Absorbent loaded with Gold thiosulfate and exhausted,Recovering Gold from Gold loaded with obsorbente Regenerating, and thiosulfate in the manner described above.
