Abstract

The article describes a perspective combined method of treatment molybdenite concentrate based on roasting with sodium carbonate and following water leaching process. This method is characterized by almost completely binding of the sulfur compounds into water-soluble sodium sulfate, conversion of molybdenite into water-soluble odium molybdate, and if concentrate contains rhenium - transform into water-soluble sodium perrhenate.

碳酸钠烧成法处理辉钼矿精矿
介绍了一种碳酸钠焙烧-水浸复合工艺处理辉钼矿精矿的前景。该方法的特点是硫化合物几乎完全结合为水溶性硫酸钠,辉钼矿转化为水溶性钼酸钠,如果精矿中含有铼,则转化为水溶性过铼酸钠。
