【Abstract】 This paper introduces a new technique for preparation of electrolytic zinc from silicon and iron rich zincite by ammonium salt process.Experimental results show that this technique enjoys a simple flowsheet,easily controlled technological conditions and a low energy consumption.The leaching rate of zinc is up to 95% if the zinc content is over 20% of the zincite.The energy consumption of direct current for zinc electrolysis is 2380～2460 kwh/tZn,and the quality of cathode zinc corresponds to the #1 zinc according toe the national standards of China (GB 470 83).更多还原
