Iron ore beneficiation process
BaYanNaoErMeng coalpit mouth pyrite mine is located in the Inner Mongolia autonomous region, is a polymetallic sulphide ore deposit of metamorphic rock. Selecting the size of 1.2 million t/a.

Undressed ore in the useful minerals are mainly pyrite, chalcopyrite, sphalerite, magnetite, magnetic pyrite and galena. The gangue minerals are mainly calcite, dolomite and quartz, and feldspar, chlorite, mica, etc.
Gold ore processing equipment
Pyrite and pyrrhotite, chalcopyrite, sphalerite close symbiosis, disseminated structure; Chalcopyrite irregular shaped more early mineral filling gaps, and part of chalcopyrite in sphalerite emulsion droplet shaped structure; Sphalerite and he shaped crystal filling or disseminated distribution in gangue; Pyrrhotite is emulsion droplet distribution in sphalerite. Undressed ore are mainly copper sulfide ore and zinc sulfide ore two types of copper, zinc mainly assumes the primary sulfide ores exist, less secondary copper and copper zinc oxide.
Iron Magnetic separation equipment
Two types of ore after many schemes of ore dressing experiments, streaming flotation process than two separate ore has obvious superiority, so use streaming flotation technology in the design of concentrator. Test of ore for zinc sulfide ore, copper sulfide ore = 2:1 mixed flotation. Without cyanide process, replace with Na2SO3 NaHSO3 separation effect.
Copper concentrator factory
The mine divided into rich ore and lean ore section, enrichment of rich ore without dressing, broken into 3 mm directly sold as a concentrate. Enrichment, lean ore flotation method is used to obtain the high grade of sulfur concentrate. For ore produced in the process of mining of low grade boundaries, the moving sieve jig and spiral separator re-election new equipment of combining the new technological process, efficient re-election from low grade pyrite stone extraction, qualified pyrite concentrate for the banded ore, the ore containing sulfur 23.15% of cases, get the sulphur concentrate grade of 35.50%, sulfur concentrate in the sulfur recovery rate of 83.36%; In density lump ore, undressed ore 23.88%, sulfur for sulfur concentrate grade of 35.00%, sulfur concentrate in the sulfur recovery rate of 78.45%.
