从铝土矿中提取镍和钴通常有两种方法 ,一种是在焙烧阶段将镍和钴的氧化物还原成金属 ,然后以氨性溶液浸出的Nicaro或 Caron法 ;另一种是对镍和钴的氧化物进行高压酸浸 ,接着用硫化物沉淀的 Moa Bay或 Sherritt法。近年来 ,采用加压酸浸和 SX- EW法从铝土矿中提取镍和钴引起了
There are usually two methods for extracting nickel and cobalt from bauxite. One is the Nicaro or Caron method of reducing the oxides of nickel and cobalt to metals in the calcination stage and then leaching with ammonia solution. The other is nickel And cobalt oxide for high pressure pickling followed by Moa Bay or Sherritt precipitation with sulphide. In recent years, the use of pressurized acid leaching and SX-EW extraction of nickel and cobalt from bauxites has caused
