摘要

以黑龙江某铜浸渣为对象,采用化学分析、XRD衍射分析、物相分析、矿物解离分析仪(MLA)等手段研究了矿石的矿物学特性。在工艺矿物学研究基础上,通过试验研究确立了重磁联合工艺回收铜浸渣中共伴生矿物金、磁铁矿、石榴子石,获得含金2.58 g/t、回收率44.66%的金精矿,含磁性铁65.16%、回收率89.34%、全铁含量67.29%的铁精矿以及产率48.15%、纯度为95%的石榴子石精矿,实现了资源的综合回收利用。
        The mineralogical properties of copper leaching residue from Heilongjiang province were studied by means of chemical analysis, XRD diffraction analysis and mineral liberation analyzer(MLA). Based on the study of process mineralogy, the combined technology of gravity separation and magnetic separation, which recovered associated gold, magnetite and garnet from the copper leaching residue, was established through experiment study. The results showed that the gold concentrate with the grade of 2.58 g/t and the recovery of 44.66%, and the iron concentrate which contained 65.16% MFe and 67.29% TFe and with the recovery of 89.34%, and the garnet concentrate with the yield of 48.15% and the purity of 95% were obtained. The technical process achieved comprehensive recovery and utilization of the resources.
