摘要
研究分析了镁质硅酸镍矿采用硫酸常压浸出工艺中浸出废液中镁的综合利用,考察了浸出过程中镁的溶出过程,采用Ca(OH)_2中和沉淀法回收浸出废液中的镁,获得了氢氧化镁与水合硫酸钙(CaSO_4·2H_2O)的混合物,其具有填充材料的特性,可作为一种填充材料使用。
The comprehensive utilization of magnesium from leach liquors of atmospheric acid leaching process for silicon-magnesium nickel ore was studied. Magnesium was recovered using hydroxide and the precipitate produced was a mixture of magnesium hydroxide and gypsum(CaSO4·2 H2 O).The mixture had the similar properties with other filler material and which was proved to be used as a filler material.
