Chromium Mining and Extraction | Chromium Mining Processing

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.

Extraction of Chromium from Chromite Ore

The average grade of the metallurgical chromite ore was 43.4 pct Cr2O3, with 52 pct of the ore having a chromium-to-iron ratio of 3:1 or over, 17.6 pct having a ratio between 2:1 and 3:1, and 30.4 pct having a ratio less than 2:1. Chemical-grade chromite ore generally ranged from 40 to 46 pct Cr2O3 with a chromium-to-iron ratio of 1.5:1 to 2:1.

Chromium Info [MarZ Chemistry]

Accordingly, chromite is often reduced with carbon in a furnace, producing the alloy ferrochromium, which contains iron and chromium in an atom ratio of approximately 1 to 2. To obtain pure chromium, chromite is first treated with molten alkali and oxygen, converting all of the chromium to the alkali chromate, and the latter is dissolved in water and eventually precipitated as sodium ...
