针对乌拉根铅锌矿生产现场锌精矿含硅高的问题，进行了降低锌精矿硅含量的小型试验研究.结果表明：水玻璃对石英、长石和黏土等硅酸盐矿物具有较强的抑制和分散作用.在水玻璃、硫酸铜和丁基黄药的用量分别为300 g/t、150～250 g/t和50～80 g/t，磨矿细度为小于0.074 mm 占49.50%～54.50%，浮选浓度为37%～40%条件下，可获得锌回收率68.84%、锌品位56.16%、锌精矿硅含量为6.45%的较好指标.经生产验证：锌精矿硅含量可由11.37%降低到7.16%.

To solve the problem of high content of silicon in the zinc concentrate in Wulagen lead and zinc ore, a small experimental study to reduce the silicon content in zinc concentrate is made. The test result shows that silicate having strong inhibition and dispersion for quartz, feldspar and clay. A proper index of zinc recovery 68.84 %, zinc grade 56.16 %, silicon content 6.45 in zinc concentrate is achieved under the condition of sodium silicate 300 g/t, copper sulphate 150~250 g/t, butyl xanthate 50~80 g/t, the -0.074 mm size-fractionated of grinding fineness accounting for 49.50 %~54.50 %. Production practice shows that the silicon content of zinc concentrate can be reduced from 11.37% to 7.16 %.
