摘　　要：针对含铬电镀污泥开展多金属资源化利用工艺研究。结果表明,电镀污泥采用硫酸浸出,Lix984N萃取铜,沉淀剂沉铬,氧化沉铁,硫化钠沉锌,碳酸钠沉镍,在优化试验条件下,铜、镍、锌和铬回收率均大于96%。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 Lix984 N,chromium elimination with precipitant,iron removal by oxidation and deposition,zinc and nickel elimination with sodium sulfide and sodium carbonate respectively.
