Chrome ore was mined in the Ingessana Hills in Al Awsat. In the late 1970s, output was reportedly more than 20,000 tons a year, of which more than fourfifths were produced by the Ingessana Hills Mines Corporation, a subsidiary of Sudanese Mining Corporation. A private operation produced the remainder.
Jun 15, 1976· Process of extracting chromium from a chromium ore or concentrate by oxidation, which comprises suspending the chromium ore or concentrate in a bath of molten salts and introducing an oxygencontaining gas into the suspension in a sufficient amount and for a sufficient amount of time to oxidize chromium therein.
Chromite ore has a spinel structure with a general formula of (Fe,Mg)O.(Cr,Al,Fe) 2 O 3. The content of Cr 2 O 3 for metallurgicalgrade chromite ore is in the range 42–55% and the chromiumtoiron ratio is higher than These quantities determine the chromium content in the smelted chromium ferroalloys.

A few larger mines hired workers and provided room and board. Most operations were small, and many investments found little return. When the grade of the chromite was low, mills were needed to concentrate the ore; miners often converted mills used for gold.
Chromite Ore Crushing. The crushing section for this 250 ton per day chrome mill consists of a coarse ore grizzly, a coarse ore bin with pan feeder to a 1''8″ reduction crusher and a crusher discharge conveyor to a crushed ore bin. On this particular ore, we find .
Chromite ore can be mined to produce chromite concentrate. It can also be crushed and processed. Chromite concentrate, when combined with a reductant such as coal or coke and a high temperature furnace can produce ferrochrome. Ferrochrome is a type of ferroalloy that is an alloy in between chromium and iron.
