锡石的回收至今仍然是以重选为主要的方法,国內外許多锡矿选矿厂中都普通采用重选法回收锡石。但是,我矿最近已試验成功了用浮选法回收锡石的新方法。从锡石硫化物矿石中浮选锡石是:先將金属硫化物浮尽,然后浮选锡石,使锡石和脉石(方解石、石英)分离,得到最終锡精矿。根据現在条件粒矿品位Sn Cassiterite recovery is still re-election as the main method, many tin concentrates at home and abroad are commonly used re-election method of recovery of cassiterite. However, my mine has recently tested a new method for the recovery of cassiterite by flotation. The flotation of cassiterite from cassiterite sulfide ore is as follows: firstly, the metal sulfide is floated out and then cassiterite is floated to separate cassiterite and gangue (calcite, quartz) to obtain a final tin concentrate. Under the current conditions of ore grade Sn
