摘　　要：对云锡某低品位难选锡矿泥开展选矿试验研究,根据试料性质,采用离心选矿机预选富集并脱泥、浮选除硫化矿物、锡石浮选的工艺流程,有效地回收了细粒锡石;流程试验获得给矿锡品位0.21%,锡精矿品位6%、泥矿系统回收率40.43%,锡石浮选作业回收率76.28%的良好指标。The aim of this work is carrying out dressing investigation Yunnan Tin Corporation. Based on the properties of the ore, a process routed separation with cen cassiterite with fine concentrate reaches floating reaches 76. trifugal, floatation for grain in the sludge 6%, 28% removal sulfides, cassiterite floating Results indicate that good index is recovery efficiency in sludge system reaches 40. 43% while the tin grade of charging ore is 0. 21%. on a low grade refractory sludge in as enrichment and de-sludge by pre- was employed to recovery effectively obtained. Which the grade of tin in , and recovery efficiency of cassiterite
