西湾精选厂堆存尾矿,含锡0.93%,主要有用矿物是锡石、黑钨矿、钛铁矿和锆英石等。试验曾用混合甲苯胂酸为捕收剂,腐植酸钠或酸性水玻璃、氟硅酸钠为抑制剂浮选锡石,得到含锡4%以上的精矿,回收率50～55%;采用重迭流程选别该堆存尾矿,获得的锡精矿含锡4.46%,回收率41.43～48.5%。虽然重选指标稍低,但经济上合算,决定采用重选工艺处理上述堆存尾矿。堆存尾矿95%—100目,主要金属矿物是磁铁矿、褐铁矿、赤铁矿、锡石等。脉石矿物以石英为主,还有少量的高岭土和柘榴子石。锡石多与赤铁矿、褐铁矿连生,各粒级锡石连生体百分数是:+
West Bay Featured Plant stockpiled tailings, containing 0.93% tin, the main useful minerals are cassiterite, wolframite, ilmenite and zircon and so on. Test had been mixed with toluene acid as collector, sodium humate or acid sodium silicate, sodium fluoride inhibitor flotation cassiterite, get more than 4% tin concentrate, the recovery rate of 50 to 55%; using The stacking process selected the tailings, the obtained tin concentrate containing tin 4.46%, the recovery rate of 41.43 ~ 48.5%. Although the reselection index is slightly lower, it is economically viable to decide on the re-election process to deal with the above-mentioned stockpiling of tailings. Storing 95% -100 mesh tailings, the main metal minerals are magnetite, limonite, hematite, cassiterite and so on. Quartz gangue minerals, there are a small amount of kaolin and garnet. Cassiterite and hematite, limonite even students, each grade cassiterite percentage is: +
