The purification process of wet zinc smelting adopts the method of adding antimony salts and zinc powder to purify the new liquid.The unit consumption of zinc powder per ton of zinc is about 70～80 kg.In order to reduce the unit consumption of zinc powder in the purification process,several new cobalt removal agents have been introduced for cobalt removal.A,B two cobalt re-moval agents are organic cobalt removal agents,and C cobalt removal agent is inorganic cobalt removal agent.Three cobalt removal agents reacted under appropriate conditions and achieved the expected cobalt removal effect.Among them,A has the lowest cost of cobalt removal agent,while B has the highest cost of cobalt removal agent.
