Grinding Machine For Copper Sulphatesodium Sulfite And Gold Leaching

We used 500 grams of commercial grade sodium cyanide and 1.5 liters of hydrogen peroxide of 36%. This solution contains 100 grams of gold around 5 grams of iron and 5 grams of solder. We want to use copper sulphate, sodium metabisulfite for cyanide and hydrogen peroxide destruction. And sodium hydro sulfite for gold recovery from the solution

    Dec 06, 2017 0.27M ammonia, 0.0014M copper, 0.00625M sulfite, and leaching for 16 hours a gold extraction of 67 pct with 2 kg thiosulfate/mt consumption would be obtained. Results from some of the response surface tests have already proven the feasibility of extracting 67 pct of the gold, but thiosulfate consumption was higher (5 – 24 kg/mt) than the

    The leaching of sulphide minerals in chloride media

    Jun 01, 1992 Leaching was carried out in a single stage near the boiling point of the ferric chloride leaching medium (around 105 C); high copper extrac- tions were realized by grinding the copper concentrate to 95% -325 mesh and by prolonging the leaching time up to 8 h. The investigators recognized that metal recovery and iron disposal were key factors
