用含氢氟酸和硫酸的含水酸溶液浸提未提纯的含硅石杂质,其含量低于10%、平均粒度小于150微米的辉钼矿精矿给料。氢氟酸的用量至少要等于与给料中的硅石发生反应所需要的量。硫酸的用量要使溶液的 PH 值保持在0～2之间。提纯后的钼产品最适合作润滑剂和用作为合成高纯度钼化合物的中间产品。
Hydrophilic hydrofluoric acid and sulfuric acid containing aqueous acid solution was used to extract unpurified silica-containing impurities, the content of less than 10%, the average particle size less than 150 microns of molybdenite ore feed. The amount of hydrofluoric acid is at least equal to the amount required to react with the silica in the feedstock. The amount of sulfuric acid to maintain the PH value of the solution between 0 ~ 2. The purified molybdenum product is best suited as a lubricant and as an intermediate for the synthesis of high-purity molybdenum compounds.
