Abstract:
      Multi metal resources utilization of chromium-bearing electroplating sludge was studied. The results show that recovery rates of copper, nickel, zinc and chromium are all 96% above under the optimum conditions of sulfuric acid leaching, copper extraction with Lix984N, chromium elimination with precipitant, iron removal by oxidation and deposition, zinc and nickel elimination with sodium sulfide and sodium carbonate respectively.
