内蒙古某地芒硝矿选矿试验研究

Experimental Study on Mineral Processing for a Mirabilite Ore in Inner Mongolia

芒硝矿主要成分为Na2SO4(59.02%)和MgSO4(20.8%),经化学提取、分离得到硫酸钠和氢氧化镁,其中硫酸钠产品含Na2SO499.52%、回收率99.89%;氢氧化镁产品含Mg(OH)298.65%、回收率99.90%。

The ore contains 59.02% Na2SO4 and 20.8% MgS04. Through a process of ＂chemistry distilling - separating＂, Na2SO4 concentrate of 99.52% Na2SO4 with a recovery of 99.89% and Mg（OH） 2 concentrate of 98.65% Mg（OH） 2with a recovery of 99.90% are obtained respectively.
