Chrome Ore Article about Chrome Ore by The Free Dictionary

Three chrome ore-bearing formations are identified: the peridotite-orthopyroxenenorite formation on the platforms and the peridotite and gabbronorite-peridotite formations in geosynclinal regions. Chrome ores are also known to occur in deluvial, eluvial, and coastal alluvial deposits. A distinction is made between metallurgical, refractory, and

Chromite Wikipedia

Chromite is a crystalline mineral composed primarily of iron(II) oxide and chromium(III) oxide compounds. It can be represented by the chemical formula of FeCr 2 O 4.It is an oxide mineral belonging to the spinel group.The element magnesium can substitute for iron in variable amounts as it forms a solid solution with magnesiochromite (MgCr 2 O 4). A substitution of the element aluminium can

Ferrochrome Wikipedia

Chromium ore (an oxide of Cr and Fe) is reduced by coal and coke to form the iron-chromium alloy. The heat for this reaction can come from several forms, but typically from the electric arc formed between the tips of electrodes in the bottom of the furnace and the furnace hearth. This arc creates temperatures of about 2,800 °C (5,070 °F).

Chromite Ore an overview ScienceDirect Topics

Chromium metal is obtained commercially by heating chromite ore in the presence of carbon, aluminum, or silicon, and subsequent purification (ATSDR, 2000). Sodium chromate and dichromate are produced by roasting chromite ore with soda ash and are the primary chromium salts from which most other chromium compounds are derived (ATSDR, 2000).

Chrome Sand Refractory Application African Pegmatite

Filler sand made primarily with chrome ore is called chromite-based sand. Its advantages include good fluidity, high density, high melting point, and resistance to over-sintering. At high temperatures, the FeO component of chrome sand forms a secondary spinel that changes the volume of the sintered layer.
