Characterization and Beneficiation of Anka Chromite Ore ...
Chromium is largely used as alloying elements in steels for production of stainless steels. It is added in form of ferrochromium, which is presently imported from Russia and Germany to meet the need of Nigerian Steel Industry. Chromite ore (FeOCr2O3) is the most important mineral occurrence of chromium, and some deposits are reported in Anka Local Government Area of Zamfara State.
9 Ore Deposits and Economic Minerals – Mineralogy
Ideal ore minerals contain of the commodity of interest. Native copper, for example, is an ideal copper ore mineral. Ideal ore minerals are, however, uncommon. The most commonly mined ores are not ideal. Instead they are rich in ore minerals that can be processed relatively inexpensively to isolate desired components.
Chromite Beneficiation Process
· Chromite Process Summary. This flowsheet is very effective due to the ability to remove the high grade chrome with very little grinding on each pass through the mill. In this way, grinding takes place with a large number of small reductions followed by immediate removal of the liberated chrome into a high grade concentrate.
Chromium Ore
This process has been operated at Chiba Steelworks, Kawasaki Steel Corporation (currently JFE Steel Corporation) since 1994. In this steelworks, stainless steel is produced by smelting reduction process of chromium ore with hot metal produced at a BF in a specialized convertertype furnace. Stainless steel dust containing Cr and Ni is generated from this smelting process.
Chromium | Minerals Eduion Coalition
Chromium (Cr) is a hard, bluish metallic element. The only ore of chromium is the mineral chromite and 99 percent of the world's chromite is found in southern Africa and Zimbabwe. Geologists estimate that there are about 11 billion tons of mineable chromite ore in the world, enough to supply the current demand for hundreds of years.

plagioclase. Chromite, the primary ore mineral, occurs in mine waste in minor amounts due to the imperfect grinding of the ore prior to producing a chromite concentrate. The processing of chromite concentrates produces a variety of chromiumbearing solid phases in .
Chromium Mining and Extraction | Chromium Mining Processing
CHROMIUM : Chromium is the brittle, lustrous and hard chemical element that belongs to the group of spinel. Chromite grains are commonly found in large mafic intrusions and are also found in metamorphic rocks on the earth's crust. Chromite, which is an iron chromium oxide (FeCr2O4) is the only ore present to produce the element chromium.

Chromite is a very important mineral because it is the only economical viable source of chromium. It is used in various appliions such as metallurgical industries, refractory industries and chemical industries [1]. Chromite ore is composed of elemental iron, oxygen and chromium and it is found in various forms, hence it is known as a spinel.
