    May 27, 2021 Chromite has weak magnetic properties, which can use strong magnetic separation. In the beneficiation of chromite ore, a medium magnetic machine is used to remove magnetite first, and then a strong magnetic machine is used to recover chromite and separate gangue minerals, which especially suitable for fine-grained minerals. Equipments:

    Conventionally, the chromite ore beneficiation is carried out using gravity concentration techniques. As the particle size decreases, the separation of the chromite particles by gravity separation becomes difficult because of the presence of near-density gangue minerals. In addition to magnetic sepa-ration, flotation has also been incorporated into the process to recover the fine chromite
