| | Based on the results of laboratory experiments and production tests, an improved oredressing process for recovering the low grade accompanying scheclites involved in flolationtailings of molybdenum ore, by preconcentration and abandonment of tailing with spirallaunder and then through gravity-flotation or gravity-gravity combined process is sug-gested. The main results of experiment and tests are analyzed and compared as well. | | 本文通过实验室试验及现场工业性试验结果,提出回收浮钼尾矿中低品位伴生钨的选矿方法,即采用螺旋溜糟预选抛尾,经重-重联合流程或重-浮联合流程综合回收白钨矿,并对各项主要试验结果进行了分析比较。 | | 文摘来源 | | The paper introduces the properties of high iron manganese ore and test results of separation Applying the combined processes of magnetic, gravity ,flotation separations, i. e,rejecting tailings with HIMS;preconcentration of manganese,flotation processes of magnetically separated concentrate can give 3 grades of manganese concentrate (33%, 30%, 25%), Manganese recovery rate goes up to 75%. Purite is recovered by gravity separation from magnetically separated tailings. The paper also explains the separation ... | | 介绍了高铁锰矿石的性质和选矿试验结果。采用磁重浮联合流程,以强磁选抛尾,预先富集锰,磁选精矿经过多次浮选精选,可得到含锰33%,30%,25%以上3个品级的锰精矿,锰收率可达75%;磁选尾矿通过重选回收黄铁矿。文章还从菱锰矿晶体结构与可浮性,氧化石蜡皂在菱锰矿表面的作用机理,石油磺酸钠与菱锰矿作用机理,硅酸钠与菱锰矿的作用机理等的研究,说明了锰与铁的分离原理。 | | 文摘来源 | | A quality phosphate concentrate and discarded tailings can be obtained for processed banded phosphate ores from Baizhu Deposit Zone of Baokang Mine by two-stage separation of Tri-Flo dense medium separators with less grinding cost. Reverse flotation of middlings and minus 1 mm slimes from dense medium separation using phosphoric acid and oxidized paraffin wax soap can bring about concentrate of P2O5 29. 45% and MgO 1. 06% with a recovery of 89. 95%. Compound phosphate concentrate of P2O5 31. 78% with a reco... | | 保康磷矿白竹矿区条带状磷块岩矿石,利用TRI—FLO重介质分选机二次分选,可以分选出高质量的磷精矿和废弃的脉石尾矿,节省了磨矿费用。重介质选的中矿与—1mm矿泥用磷酸、氧化石蜡皂反浮选,可得到P_2O_529.45%,MgO1.06%,作业收率89.95%的浮选精矿。重—浮联合流程的混合磷精矿P_2O_531.78%,收率88.28%。 | | 文摘来源 | |   | | << 更多相关文摘 |
