摘要
简述氧化铜处理的现状,介绍某铜尾矿浮选的条件和结果,讨论磨矿细度,药剂用量对某铜尾矿浮选的影响。两次粗选、一次扫选、两次精选的开路试验结果表明,在磨矿细度为95%-74μm、硫化钠3000g/t、丁基黄药300g/t、羟肟酸80g/t、松醇油60g/t、pH值8.5左右、矿浆浓度30%、浮选时间20min的条件下可以得到品位18.63%的铜精矿,铜回收率53.28%,试验效果良好。
This paper reviewed the current situation of mineral processing of oxidized copper ore and introduced the condition and some issues of some copper tailings flotation. The effect of grinding and reagent consumption on flotation is discussed in this paper. As the open circuit test of two time coarse concentrating, one scavenging and two time cleaning result indicated that a copper concentrate with a grad of 18.63% Cu concentrate and a recovery of 53.28% can be obtained under the test condition as follow： grinding fineness is 95%, 0.074mm, sodium sulphide 3000g/t, butyl xanthate 300g/t, salicylhydroxamic acid 80g/t, pine oil 60g/t, pH value 8.5, the flotation time was 20 min, and the pulp density was around 30%. The test results is good.
