摘要
云南个旧是我国主要的锡矿区。该矿区矿石绝大多数是难选的残坡积砂锡矿。采用云南锡业公司研制的离心选矿机选别上述矿区的锡矿泥,能获得满意的指标。对于锡矿泥而言,它的单机处理能力为30～35(吨/日·台)。当处理含 Sn0.2～0.6%的锡矿泥时,能获得富集比2.5～3.0,回收率80～85%的精矿。+10微米粒级的回收率75～90%,-10微米粒级的回收率可达到35～40%。
Gejiu city in Yunnan Province is the principal tin ore district in our country. The overwhelming majority of ores in this district are the refractory eluvial placer tin ores.Separation of tin ore slimes in the district by use of the centrifugal separator developed by Yunnan Tin Mining Company can achieve good results.As far as tin ore slime is concerned,throughput is 30～35 metric ton per unit per day.When treating tin ore slime assaying 0.2～0.6% Sn,a concentrate of concentration ratio 2.5～3.0,with a recovery of 80～85% can be obtained.For size fraction+10μ,reco- very is in the range of 75～90%;for size fraction-10μ,recovery 35～40% is achieved.
