Part of ISSN: 08926875Separation of Ag and Cu from Their Aqueous Thiosulfate ,In recent years, there has been renewed interest in the use of thiosulfate as a substitute for cyanide in silver leaching. Copper thiosulfate leaching without ammonia was applied to extract silver from silver sulfide, resulting in the production of Ag–Cu polymetallic thiosulfate complexes in solutions. It is necessary to separate Ag–Cu
The dissolution of silver with thiosulfate and copper ions was studied in a batchstirred reactor at 25 °C in the absence and presence of various ammonium ions and oxygen concentrations in the aqueous solution.
