摘　　要：对转底炉炉灰酸浸净化液电沉积锌的工艺条件和参数进行了研究,获得的电积锌最佳电积条件与参数为:锌离子浓度50 g·L^(-1),电解液pH=2,电解温度40℃,电流密度600 A·m^(-2),骨胶浓度6 mg·L^(-1)。在最佳条件下,锌电沉积电流效率接近90%,电积出的锌表面光滑平整,其纯度可达99.9%。Conditions and parameters for zinc electrodeposition and acid leaching purification of rotating hearth furnace dust were investigated. The optimum technological conditions of zinc electrodeposition were zinc ion concentration of 50 g·L-1,electrolyte solution with pH 2,electrolysis temperature of 40 ℃,current density of 600 A·m-2,and bone glue concentration of 6 mg·L-1. Under these conditions,the zinc electrolysis current efficiency is about 90%,with a 99. 9% pure,smooth,and flat surface of electrodeposited zinc.
