摘要

针对缅甸某含锡3.80%的锡矿石进行了浮选工艺试验研究。在磨矿细度为-74μm粒级占74.20%,调整剂硫酸铵用量4 000 g/t、捕收剂DW271用量1 800 g/t、辅助捕收剂P86用量100 g/t条件下,经一粗二扫二精闭路浮选试验获得了锡精矿品位42.80%、锡回收率89.09%。
        Experiments were carried out to beneficiate tin minerals from a Burmese tin ore with Sn grade of 3.80%. With the grinding fineness of-74 μm 74.20%, and with the dosage for regulator ammonia sulfate, collector DW271 and subsidiary collector P86 as 4 000 g/t, 1 800 g/t and 100 g/t, respectively, a tin concentrate grading 42.80%Sn at 89.09% recovery was obtained by adopting a closed-circuit flowsheet consisting of one stage of roughing, two stages of scavenging and two stages of cleaning.
