| Abstract: |
| The 100 t/d industrial experiments for tail water from whole mud cyanidation process were carried out. New technologies of nanofiltration, and reverse osmosis two-step concentration of complex ions of copper and silver were developed. Activation of free cyanide, improvement of leaching rate of gold and silver, comprehensive recovery of electro-deposit copper were realized through replacement, neutral extraction, acidic stripping, and electrowinning without changing physical and chemical properties of tail water. |
