含镍、钴红土矿的处理方法是大家所知道的。红土矿中经过还原焙烧而未除去的硫一般为0.1～0.2%左右。当用氨——碳酸铵溶液浸出时,大部分硫即溶解,通常浸出液中含镍10—15克/升、硫1克/升。从此浸出液中沉淀的碱式碳酸镍直接用氢还原,最终的产品镍中 Nickel, cobalt laterite processing method is known to everyone. The amount of sulfur which is not removed after reduction roasting in laterite ore is generally about 0.1 to 0.2%. When leached with ammonia-ammonium carbonate solution, most of the sulfur is dissolved, usually 10-15 g / l of nickel and 1 g / l of sulfur. The basic nickel carbonate precipitated from the leachate is directly reduced with hydrogen to the final product nickel
