緒言目前,从溶液中采用氢还原金属的湿法冶金工艺正在四个工厂中成功地运用。加拿大舍利特·高尔顿矿业公司萨斯喀彻温堡冶炼厂,采用氢还原法从含有金属的硫酸氨络合物生产系统中,每天生产45吨镍粉、1.5吨钴粉,和各种含镍或钴的混合金属粉以及特种铜粉。少量具有一定物理特性的镍粉,也是采用氢还原 INTRODUCTION Hydrometallurgy processes that use hydrogen to reduce metals from solutions are currently being successfully used in four plants. Saskatchewan smelter at Sheriden Galton, a Canadian mining company, produces 45 tons of nickel powder, 1.5 tons of cobalt powder, and various kinds of metal from the metal-containing ammonium sulfate complex production system using hydrogen reduction Nickel or cobalt containing mixed metal powder and special copper powder. A small amount of nickel powder with certain physical characteristics, but also the use of hydrogen reduction
