Abstract Scope Pressure acid leaching residue of zinc sulfide concentrate contains abundant elemental sulfur that has excellent natural hydrophobicity, and thus it is considered an important secondary resource for recovering elemental sulfur with froth flotation technique. However, the separation of elemental sulfur from sulfide minerals in the residue is difficult mainly because of their similar hydrophobicity. In this research, we proposed an effective flotation process for selective recovery of elemental sulfur from a pressure acid leaching residue of zinc sulfide concentrate. After one-time blank rougher, two-time agent-added roughers and two-time cleaners separately using O-isopropyl-N-ethyl thionocarbamate as the collector and combined agent Na2SO3+ZnSO4+Na2S as the inhibitor, 99.9% of the elemental sulfur was recovered and the purity of concentrate product achieved 83.5%. Most of the lead, zinc and silver went into the tailing that can be used as the raw material of pyrometallurgical lead smelting for recovering these valuable metals.
