| titleOfInvention | High-alkali flotation-followed-magnetism-based beneficiation method for pyrrhotite containing magnetism |
| abstract | The invention belongs to the technical field of metal mineral resource development, and particularly relates to a beneficiation method for pyrrhotite-containing ore, which comprises the following steps: carrying out a copper flotation roughing process on the magnetite-containing ore, and carrying out a copper flotation concentrating process on the obtained copper flotation concentrate; performing a copper flotation scavenging process on the tailings obtained by the copper flotation roughing process; performing a sulfur roughing flotation process on the tailings obtained by the copper flotation scavenging process; performing a sulfur flotation scavenging process on the tailings obtained by the sulfur roughing flotation process; and (3) carrying out a magnetic separation process on the tailings obtained by the sulfur flotation scavenging process to obtain iron ore concentrate. The invention is especially suitable for the pyrrhotite containing low copper and high sulfur iron, the process adopts high alkali first floating and then magnetic dressing, and can comprehensively recover valuable metals in the copper-iron ore, including metallic substances such as copper, iron, sulfur, pyrrhotite and the like. |
