摘要
对优先浮铅流程中抑制剂的种类和用量进行了试验研究。通过对抑制剂单一使用和混合使用的对比试验,最终选择在碱性条件下,碳酸钠与硫酸锌的最佳配比为200:800,闭路试验获得的铅精矿中铅品位为51.11%、金精矿中金品位23.32 g/t,铅回收率为76.69%,金和银的总回收率分别为81.03%和75.69%。
The test researches of type and dosage of depressant in the lead preferential flotation have been conducted. By the contrast of single and mixture usage of depressant, the optimum ratio of sodium carbonate and zinc sulfate was 200：800 under alkaline condition, and the lead concentrate grading 51.11% Pb was obtained with recovery of 76.69% while the gold concentrate containing 23.32 g/t Au, and the total recovery of gold and silver reached 81.03% and 75.69% respectively.
