本文介绍从铜阳极泥中回收金银的全湿法流程。阳极泥用NaClO_3在盐酸溶液中氯化(温度85—90℃),金入溶液;经仲辛醇萃取,草酸反萃取则得到金粉。氯化渣氨浸(常温),银进入浸出液,再经水合肼还原就得到海绵银。 This article describes the whole wet process for the recovery of gold and silver from copper anode slime. Anode mud with NaClO_3 in hydrochloric acid solution of chloride (temperature 85-90 ℃), gold into the solution; by the secondary octanol extraction, oxalic acid extraction was gold powder. Ammonia chloride leaching residue (room temperature), silver into the leaching solution, hydrazine hydrazine reduction by sponge silver.
