小型试验必须查明,用何种方法才能选别萨克森矿脉的硫化斯卡隆矿石。金属矿石主要是磁铁矿、闪锌矿、磁黄铁矿、黄铁矿、白铁矿、黄铜矿、方铅矿、砷黄铁矿、斜方砷黄铁矿和锡石,它们细粒共生。表明,主耍含磁铁矿和闪锌矿的矿石用浮选方法可以选出硫化物。如果矿石还含大量黄铜矿和方铅矿,则用优先浮选法较为适合。混合浮选可回收92—97％闪锌矿和黄铜矿,优先浮选可回收70—85％到合格精矿中。以后的磁选可获得含60—65％铁的产品。经摇床选别,最后获得商品锡精矿。
Small trials must find out the means by which the sulphide carnassite ore from the Saxony vein can be selected. The metal ores are mainly magnetite, sphalerite, pyrrhotite, pyrite, white iron ore, chalcopyrite, galena, arsenopyrite, rhombic arsenopyrite and cassiterite, which are fine Granules symbiotic. It shows that the flotation method can be used to select sulfides mainly from the ore containing magnetite and sphalerite. If the ore also contains a large number of chalcopyrite and galena, the preferred flotation method is more suitable. Mixed flotation 92-97% sphalerite and chalcopyrite can be recovered, the priority flotation can be recycled 70-85% to the qualified concentrate. After the magnetic separation can be obtained with 60-65% iron products. Selected by the shaker, the final product tin concentrate.
