本研究对含砷氧化铜物料采用两段逆流硫酸浸取－铁（Ⅲ）和碳酸钙除砷－乙腈低温催化氢还原和歧化分解的处理工艺，有效地实现铜砷分离，减少砷的污染，回收其中的铜，并制得分散性好、粒径小于50μm的铜粉．
In this study, two phases of countercurrent sulfuric acid leaching-iron (Ⅲ) and calcium carbonate were used to catalyze the hydrogen reduction and disproportionation process of arsenic-containing copper oxide at low temperature to effectively separate copper and arsenic, reduce the pollution of arsenic, Recycling copper, and prepared good dispersion, particle size less than 50μm copper powder.
