摘要
采用 730E新起泡剂对汤丹铜矿的一般氧化铜矿、高结合率氧化铜矿和碳质板岩铜矿 3种矿样进行了浮选试验。结果表明 ,730E与汤丹铜矿生产所用起泡剂 2 # 油相比 ,在精矿品位相近或略有提高的情况下 ,可使汤丹铜矿 3种矿石的回收率分别提高 3 2 6、1 4 5和 2 84个百分点。通过试验 ,认为选择优良的起泡剂是提高氧化铜矿回收率的重要措施之一 ,指出在浮选新药剂的研究方面应对起泡剂给予足够的重视。
New 730E frother was used in the flotation tests of common oxidized copper ore, oxidized copper ore with high combination rate and carbonaceous slabby rock copper ore of Tangdan Copper Mine. The results showed that, compared with 2 # oil,the frother presently used in the production in Tangdan Copper Mine, 730E frother could raise the recovery of the three ores by 3.26, 1.45 and 2.84 percentage points respectively at a similar or slightly higher concentrate grade. It is concluded through the tests that selection of a fine frother is one of the important measures for raising the recovery of oxidized copper ore. It is pointed out that frother should be given sufficient attention in the research of new agents.
