| titleOfInvention | Copper-containing magnetite ore sorting method |
| abstract | The invention provides a method for sorting copper-containing magnetite ores, which solves the problems of high copper loss rate, high possibility of exceeding the standard of sulfur content of iron ore concentrates and the like in the traditional magnetic separation process of firstly magnetizing and then floating. The technical scheme of the invention is carried out according to the following modes: (1) after grinding, the raw ore is firstly subjected to weak magnetic rough separation, and then part of the raw ore is subjected to weak magnetic rough separation to obtain weak magnetic separation tailings, and the other part of the raw ore is fed into a magnetic field screening machine for fine separation to obtain iron ore concentrate and magnetic field screening machine tailings; (2) and carrying out flotation on the low-intensity magnetic separation tailings and the tailings of the magnetic field screening machine to obtain copper concentrate and tailings. The invention aims at the copper-containing skarn type magnetite ore, the method of weak magnetic roughing-magnetic field screening machine fine concentration is adopted to recover iron, and the magnetic separation tailings are subjected to flotation to recover copper. After iron is separated by magnetic separation, the copper flotation grade is greatly improved and the copper flotation treatment capacity is reduced on the premise of ensuring the copper recovery rate, so that the production cost is greatly reduced and the low-grade accompanying copper can be efficiently and economically recovered. |
