为提高紫金山金铜矿中伴生金的回收.采用闪浮加一次粗选的抑硫浮铜工艺,在不影响铜回收率的条件下,通过调节浮选矿浆质量分数、加入BP捕收剂及脉石抑制剂HY提高金的回收率.在矿浆pH值为10.5、丁胺黑药用量为25 g/t、BP用量为14 g/t、2号油用量为3 g/t、HY用量为25 g/t时,可以得到铜的回收率为85.02%、金的回收率为52.50%的铜精矿,该药剂制度可有效提高铜、金的回收率,达到提高铜矿中伴生金回收的目的.
In order to improve the recovery of associated gold in Zijinshan gold-copper mine, the flocculation plus one rougher was used to suppress the copper recovery by adjusting the mass fraction of flotation pulp and adding BP collector And gangue inhibitor HY to improve the recovery rate of gold.Under the pH value of 10.5, the dosage of butylamine black is 25 g / t, the dosage of BP is 14 g / t, the dosage of oil 2 is 3 g / t, HY When the dosage is 25 g / t, the recovery rate of copper is 85.02% and the recovery rate of gold is 52.50%. The system can effectively increase the recovery rate of copper and gold, Recycling purposes.
