Abstract: 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.
