摘要
环烷酸对萤石和重晶石的捕收能力存在一定差异，淀粉硝酸钙组合药剂能够进一步扩大这种差异。浮选试验结果表明，组合药剂既能提高环烷酸对萤石的捕收能力，又能加强淀粉对重晶石的抑制能力。在ｐＨ０为５７，环烷酸浓度为５×１０－５ｍｏｌ／Ｌ，淀粉浓度为３ｍｇ／Ｌ，硝酸钙浓度为１×１０－４ｍｏｌ／Ｌ条件下，对含ＣａＦ２９１３％，ＢａＳＯ４４９６％的混合矿样进行浮选，可获得含ＣａＦ２９８６７％，回收率９７９５％的萤石精矿。
The test results in this paper show that the mixture of starch calcium nitrate can improving the selectivity of naphthenic acid (NPA) collecting fluorite and barite in flotation. This mixture has a double function, i. e. improving the ability of NPA to collect fluorite and enhaneing the ability of starch to depress barite.
