| 摘 要： | 为了更准确的找出最优的试验条件,本文采用RSM对高氧化率铅锌矿浮选中选锌的条件试验结果进行分析,得到最优试验条件为：碳酸钠624.68g/t、六偏磷酸钠1200g/t、硫化钠6.01kg/t、十八胺200g/t。并在此基础上进行铅、锌浮选的闭路试验,获得铅精矿中Pb品位52.22%,回收率92.07%,锌精矿中Zn品位38.10%,回收率89.46%的理想指标。可供作为铅锌矿选别及RSM在选矿试验中的应用提供参考。

| Abstract: | In order to find out the best experimental conditions and make it more accurately, this article uses the RSM to analyze the test results of zinc experimental conditions in the high oxidation rate lead-zinc ore flotation tests, the optimal test conditions are: sodium carbonate 624.68g/t, sodium hexametaphosphate 1200 g/t, 6.01 kg/t sodium sulfide, and 200 g/t octadecylamine. On the basis above, closed-circuit tests of lead and zinc flotation were conducted to obtain the ideal indicator of lead concentrate with Pb grade is 52.22%, the recovery of Pb is 92.07%, Zn grade is 38.10% in zinc concentrate, and the recovery of Zn is 89.46%. It can be used as a reference for recovery of lead-zinc mines and the application of RSM in beneficiation tests. |
