摘要
某钼矿为硫化钼和氧化钼混合矿石,矿石氧化率高达68.5%。研究表明,以水玻璃为矿泥分散剂、煤油为捕收剂浮选硫化矿,以改性水玻璃为脉石抑制剂、RT为氧化钼矿捕收剂优先浮选硫化矿再浮氧化矿,可从含Mo 0.34%原矿中,获得品位46.41%的硫化钼精矿,品位27.65%的氧化钼精矿;钼总回收率78.01%。
A mixed ores consists of molybdenum sulfide and molybdenum oxide and main mineral was molybdenum oxide. Its oxidization rate of Mo was as higher as 68.5%. Research of minerals processing experiment suggested a flotation flowsheet, which consists of selective flotation of molybdenum sulfide using kerosene as collector, sodium- silicate as dispersant of slimes, then flotation of molyb- denum oxide using modified sodium - silicate as depressant of gangue, Rt as collector. The result indicated that a molybdenum sulfide concentrate of 46.41% Mo and a molybdenum oxide concentrate of 27.65% Mo are obtained from the run -of-mine ore of 0.34%Mo with a total recovery of 78.01%.
