某金矿甲坑口矿石含鎢、锑、金有川矿物,脉石矿物以石英为主,其次为方解石、磷灰石、白云母和绢云母等。选厂采用重-浮联合流程。摇床回收少量粗粒鎢、锑、金后,尾矿再磨,先浮细粒锑、金,然后再浮白鎢矿。白鎢浮选粗精矿用彼得罗夫法精选,然后酸浸除磷得最终精矿。选厂试图用氧化石腊皂代替油酸,试验结果表明,氧化石腊皂(731或733)虽可在10℃以下进行浮选,但粗精矿品位低,用彼得罗夫法精选
A gold mine pit mouth ore containing tungsten, antimony, gold Youchuan minerals, gangue minerals to quartz, followed by calcite, apatite, muscovite and sericite. Selection plant using heavy - float joint process. Shaker recovery of a small amount of coarse particles of tungsten, antimony, gold, tailings and then grinding, the first floating fine particles of antimony, gold, and then floating white scheelite. White flotation flotation crude concentrate Petrov method selection, and then acid leaching phosphorus final concentrate. The mill tried to replace the oleic acid with the oxide of the pyrite, and the test results showed that although the fossil wax (731 or 733) can be flotated at below 10 ℃, the crude concentrate has low grade and is selected by the Petrov method
