Chromium Ore - an overview | ScienceDirect Topics

Thus, an ore rich in iron oxide will have high reducibility at relatively low temperatures. Accordingly, the reduction of chromic oxide in such ores will also occur at relatively lower temperatures with the likely formation of a carbon-rich chrome carbide (Cr 3 C 2 or Cr 7 C 3) known to be stable at lower temperatures.

Chromite - an overview | ScienceDirect Topics

Magnetic concentration in a weak field is also used to extract magnetite from chromium ore before flotation or to extract it from chromium concentrate after flotation (Kurochkin, 1988; Lyakishev and Gasik, 1998). Wet high-gradient magnetic separation is usually thought to be the most promising method for improved performance.

Chromium(III) oxide | Cr2O3 - PubChem

The intestinal absorption of trivalent and hexavalent chromium (Cr) given orally (experiment I) or infused in the intestine (experiment II) was investigated in rats. The nonabsorbable form of chromium ((51)Cr2O3) and water-soluble and more absorbable Na2(51)CrO4 (the hexavalent form of Cr) were compared.Total retention of chromium given orally ranged around 15 percent
