摘　　要：云锡文山锌铟冶炼有限公司湿法炼锌工艺采用锑盐净化法净化中上清液,该工艺中,锌粉单耗是最为重要的经济技术指标,每增加1 t锌粉消耗,增加的成本约为6000元。目前,国内生产吨锌锌粉单耗普遍为50~60 kg/t,该公司通过采取控制中上清液质量及供应、溶液p H值、反应温度、反应时间、锑盐加入量、锌粉粒度,及精细化操作等措施,将锌粉单耗由60 kg/t左右降至48 kg/t左右,节约生产成本达700多万元,而且新液一次合格率、新液质量等指标明显提升,经济效益显著,其经验可为湿法炼锌企业提供一定的借鉴。Yunxi Wenshan Zinc Indium Smelting Co.,Ltd.use antimony salt purification method to purify the supernatant in zinc hydrometallurgy.In this process,the unit consumption of zinc powder is the most important economic and technical index,and for every additional 1 t of zinc powder consumption,the increased cost is about6000 yuan.At present,the domestic zinc powder unit consumption is generally 50~60 kg/t.The company adopted measures to control the quality and supply of the supernatant,the pH value of the solution,the reaction temperature,the reaction time,the amount of antimony salt,the particle size of the zinc powder,and the refined operation to reduce the zinc powder unit consumption from about 60 kg/t to about 48 kg/t,saving more than 7 million yuan in production costs.In addition,the primary qualification rate of the new liquid and the quality of the new liquid have been significantly improved,and the economic benefits are significant.Its experience can provide a certain reference for hydro zinc smelting enterprises.
