通过对某企业自产钼精矿进行氨加压浸出依赖性参数试验研究和分析,得出了优化条件.综合试验表明,钼精矿经氨加压浸出后,钼、铼、铜的浸出率分别可达96％、98％和60％以上.氨浸液经酸沉后,钼酸铵结晶率可达98％以上.溶剂萃取试验表明,含铼滤液通过两段萃取和反萃取后,铜、钼、铼将得到彻底分离,铼的萃取率可达98％以上,经二次反萃之后,溶液中铼可富集到20 g/L以上,为铼的进一步提纯创造了有利条件.%Based on the experimental study and analysis of the dependent parameters of ammonia pressurization leaching for molybdenum concentrate produced by an enterprise, the optimum conditions are obtained. The comprehensive test shows that the leaching rate of molybdenum, rhenium and copper can reach above 96％, 98％ and60％, respectively. The crystallization rate of ammonium molybdate can reach above 98％ after the ammonia leaching solution is settled by acid. The solvent extraction test showed that after the rhenium filtrate was extracted by two-stage extraction and reverse extraction, copper, molybdenum and rhenium were completely separated, and the extraction rate of rhenium could reach over 98％. After the second reverse extraction, rhenium could be enriched to more than 20 g/L in the solution, creating favorable conditions for further purification of rhenium.
