从含镍废触媒中回收镍的工艺实验

Nickel Reclamation from Waste Nickel-Accelerant

摘要: 合镍废触媒原料经H2S04二次浸取，调节PH值，加沉淀剂除铁、重金属、铝等杂质，蒸发结晶，生产硫酸镍，产品质量达到国家一类标准，镍的总回收率达到92．3％。

Abstract: A method for nickel reclamation from waste nickel accelerant was developed. Raw material containing waste nickel accelerant was dissolved in sulfuric acid. In appropriate acidity, nickel was separated from iron, aluminum, heavy metals and other impu
