摘要
对某MgO品位11.86%、S品位6.81%的高含镁铜硫矿石进行了选矿试验研究。采用部分优先浮选铜、铜硫分离、铜精矿反浮选脱镁的浮选流程,使用选择性强的铜捕收剂SG-2并配合使用镁质脉石抑制剂HD,获得了Cu品位23.47%、MgO品位2.99%、Cu回收率81.10%的合格铜精矿。
An experimental study was carried out for mineral processing of a Cu-S ore with grade of MgO at 11.86%, grade of S at 6.81%. In the experiment, a flotation process, consisting of preferential flotation of copper, Cu-S separation and reverse flotation of copper concentrate for removal of magnesium, was adopted, with SG-2 as a copper collector in combination with HD as a depressant for magnesium-containing gangue, producing a standard copper concentrate grading 23.47% Cu and 2.99% MgO, with copper recovery at 81.10%.
