滇西锡铁多金属矿工艺矿物学研究
TD912; 针对滇西某复杂锡铁多金属矿,采用矿物参数自动分析(MLA)和传统工艺矿物学分析相结合的方式进行工艺矿物学研究,系统研究了矿石的化学成分、矿物组成、主要矿物赋存状态以及解离程度.结果表明:样品中的金属矿物主要是磁铁矿,含量为31.31％,其次为闪锌矿和锡石,含量分别为0.44％、0.21％.MLA统计分析结果显示,大部分磁铁矿和闪锌矿嵌布粒度在-75～+19μm之间,其理论回收率分别为75.03％、61.14％;锡石主要分布在-19 μm,其分布率为60.83％,其余锡石主要分布在-38～+19 μm,传统选矿难以直接回收利用,可采用硫化挥发或还原焙烧法回收锡.通过系统工艺矿物学研...

| Abstract_FL | The process mineralogy was studied by combining Mineral Liberation Analysis(MLA)with traditional process mineralogy techniques for a complex tin-iron polymetallic ore in western Yunnan,China.Chemical constituents,mineral composition,occurrence state of main minerals and liberation degrees of the ore were systematically studied.The results showed that the ores were mainly composed of magnetite,sphalerite and cassiterite,with their contents of 31.31％,0.44％and 0.21％,respectively.The statistical results of MLA presented that a large parts of magnetite and sphalerite were distributed in the grain size ranging from-75 μm to+19 μm,and their theoretical recoveries were 75.03％and 61.14％,respectively.The distribution rate of cassiterite which was mainly distributed in the grain size of-19 μm reached 60.83％.The rests of cassiterite were mainly distributed in the grain size range of-38 μmm to+19 μm.The results indicated that it is difficult to recover metallic tin viatraditional beneficiation technologies.Other methods such as sulfidation roasting and reduction roasting may be adopted.It lays a solid foundation for comprehensive,efficient and cleaner utilization of tin-iron polymetallic ore in western Yunnan after the systematic research. |
