Chromite gravity separation+magnetic separation+electric separation process

Chromite gravity separation+magnetic separation+electric separation process

At present, more than 50 types of chromium containing minerals have been discovered in nature, belonging to the categories of oxides, chromates, and silicates; Chromite is currently the only mineral in industrial production, mainly composed of iron magnesium chromite, magnesium iron chromite, aluminum iron magnesium chromite, etc. The selectivity of chromite mainly depends on its grade, embedded particle size, and gangue composition. Currently, mineral processing methods include gravity separation, magnetic separation, electrical separation, flotation, roasting magnetic separation, etc.

Re selection+magnetic separation+electric separation process: After the raw ore is crushed and ground, a portion of the tailings are first discarded through re selection to obtain coarse concentrate products. The coarse concentrate products are further enriched through magnetic separation, and then dried and electric separation to obtain high-quality concentrate.

Process characteristics: High product grade and low environmental pollution.

Typical beneficiation plant

Papua New Guinea chromium ore beneficiation plant, the deposit belongs to coastal placer deposits, formed by the weathering of the primary ore and river alluvial deposits; The main chromium containing minerals are chromite and chromite spinel, while the main gangue minerals are olivine, pyroxene, etc. The specific process is as follows:
