Abstract

The processing of molybdenum concentrate by roasting with caustic soda in the absence of air was investigated with recovery of the principal components, molybdenum and sulfur. After leaching and filtration of the roasted product, molybdenum was recovered in the filtrate as Na₂MoO₄, whereas sulfur was recovered as Na₂S. The process completely eliminates the emission of sulfur-containing gases into the atmosphere.

无空气条件下烧碱处理钼精矿的研究

研究了在无空气条件下烧碱焙烧钼精矿的工艺，回收了主要成分钼和硫。焙烧产物经浸出过滤后，滤液中钼以Na2MoO4的形式回收，硫以Na2S的形式回收。这个过程完全消除了向大气中排放含硫气体。
