【摘要】 云南某含锡磁铁矿,原矿铁品为42.83%.铁主要以磁铁矿形式存在;锡品位化为0.57%,锡主要以锡石形式存在。采用弱磁选一摇床重选联合流程进行选矿试验,获得铁精矿、锡精矿1、锡精矿2这3种产品。铁精矿铁品位为66.01%,铁回收率为83.03%;锡精矿1锡品位为41.95%,锡回收率为17.54%;锡精矿2的锡品位为8.28%,锡回收率为15.79%,可送冶炼厂用烟化法回收Sn。试验结果为该矿床的开发利用打下了基础。更多还原

【Abstract】 A Yunnan tin-containing magnetite ore contains 42.83% iron mainly in magnetite anti 0.57% tin mainly in cassiterite.Beneficiation test was made on this ore using a combined process of low intensity magnetic separation and ta- ble concentration,and obtained three pruducts:iron concentrate grading 66.01% with an iron recovery of 83.03%;tin concentrate No.1 grading 41.95% with a tin recovery of 17.54%;and tin concentrate No.2.grading 8.28% with a tin re- covery of 15.79%,which can be sent to the smelter for recovering Sn by fuming process.The test results have laid a foun- dation for the exploitation and utilization of this deposit.更多还原
