摘要
针对黑色页岩型银钒矿的矿物特点,确定了除炭富集银精矿的浮选制度,并对分离后的钒矿进行了焙烧-浸出试验,实验表明,采用钙化焙烧-酸浸和钙化焙烧-碱浸2种方法处理该类矿都可以达到较理想的浸出效果,钒浸出率分别达到74.5%和65%。
The beneficiation technology of decarbonization ＆ enrichment of silver was determined on the basis of the characteristics of the black shale-hosted silver and vanadium deposits, and the roasting-leaching test was conducted for the separated vanadium ore. The experimental results show that the ideal leaching results can be obtained by using two methods of CaO roasting-sulphuric acid leaching ＆ CaO roasting-alkali leaching while processing this kind of deposit, and the leaching rate of vanadium is up to 74.5% and 65% respectively.
