E908捕收剂优先浮选高硫含铜矿石的试验研究

Study on selective flotation of copper ores with high sulfur content using E908 collector

摘要: 在低碱度条件下,研究了以E908为捕收剂,腐殖酸钠为抑制剂对某高硫含铜矿石的优先浮选工艺。试验结果表明,捕收剂E908对硫化铜矿具有较好的捕收性能,腐殖酸钠是铜硫浮选分离时黄铁矿的优良抑制剂。全优先流程闭路试验得到铜精矿铜品位19.87%、银品位605.84g/t,铜回收率87.76%、银回收率84.51%的浮选指标。

Abstract: Study on the differential flotation of copper ores with high sulfur content in weak alkali medium using E908 collector, humic acid sodium salt depressor. The test results show that, compared with other reagent, E908 collector shows a higher collecting capacity and a better selectivity, humic acid sodium salt are taken as a highly effective depressant to the pyrite in flotation of copper ores. The result of whole closed circuit gained the copper concentrate with copper grade and recovery 19.87% and 87.76%, and obtained silver grade and recovery 605.84g /t and 84.51%.
