摘　　要：云锡公司某600t/d锡铜共生硫化矿生产系统,由于铜矿物结晶粒度变细,铜硫分离细磨工艺不能使铜矿物充分单体解离,造成铜精矿品位及回收率下降。采用新型细磨介质和介质尺寸精确化优化设计后,提高了细磨效果,改善了产品特性,进而稳定和提高了铜精矿品位及回收率,并降低了介质消耗。在原矿品位相近时,铜精矿品位提高了0.97%;回收率提高了7.2%;介质的单耗由0.068kg/t降为0.06kg/t,下降11.76%;抑制剂石灰单耗由4kg/t降至3kg/t、亚硫酸钠单耗由0.4kg/t降至0.2kg/t、漂白粉单耗由0.4kg/t降至0.2kg/t、腐钠单耗由0.2kg/t降至0.1kg/t,下降的幅度较为明显。A ＂flotation - re-election＂ joint process of fine-grained disseminated cassiterite, a mineral component complex cassiterite Refractory Ore research, analysis ore properties, examine the ＂flotation - reelection＂ and ＂mixed flotation - re-election technical and economic indicators ＂in two of the process. The results show that： flotation - re-election process tin comprehensive recovery of 40.43%, copper recovery of 65.87%, with the bulk flotation - re-election process as compared to 2.49% tin comprehensive recovery rate is low, copper recovery 4.2% higher; flotation - re-election process of processing a tonne of ore gross profit was 58.46 yuan, compared with flotation -re-election process more revenue 13.93 yuan. So, from both technical and economic indicators index for refractory Cassiterite Ore, should adopt preferential flotation - re-election process.
