摘　　要： 对某含铁21.77%、铜0.20%、硫1.03%的尾矿砂的化学成分及主要矿物物相进行了分析,并针对性地制定了铁、铜、硫回收试验的弱磁—强磁—还原焙烧—弱磁—铜硫混浮—铜硫分离原则流程,在试验确定的最优工艺技术条件下,获得了产率20.39%、铁品位61.62%、回收率57.71%的铁精矿,铜品位14.57%、回收率3.21%的铜精矿,硫品位38.21%、回收率10.95%的硫精矿。得出铁矿物回收经济效益显著、铜硫矿物回收效益不理想的结论。 The chemical composition of tailings sands with Fe 21.77%,Cu 0.20%,S 1.03% and the phase of main mineral were analyzed,and then a process of low intensity magnetic separation-high intensity magnetic separation-reduction roasting-low intensity magnetic separation-bulk flotation of copper and sulfur-separation of copper and sulfur is made to get Fe,Cu and S.Under the optimal technical conditions obtained from tests,iron concentrate with a yield of 20.39%,Fe grade of 61.62%,Fe recovery of 57.71%,copper concentrate with Cu grade of 14.57%,Cu recovery of 3.21%,and Sulfur concentrate with S grade of 38.21% and S recovery of 10.95% are achieved.The conclusion is that the recovery of iron minerals reaches remarkable economic benefits,but the recovery of copper and sulfide minerals are not ideal.
