Process for extracting chromium from chromium ores ...

The commonest of these ores is chromite, a natural oxide of iron and chromium, which in some cases contains oxides of magnesium, aluminum and silicon. Chromium is generally extracted from its ores by oxidation in the form of chromate, in which state its valence is six. The product of this reaction is then treated to extract the chromate. The chromate in solution is acidified with sulfuric acid ...

Chromite - an overview ScienceDirect Topics

Chromite is the main source of chromium, an essential alloy of stainless steel, that provides corrosion-resistant properties to the metal. The iron-chromium product used to make steel is called ferrochromium and this is the common form in which the metal is traded. Because of solid solution, the Cr content of chromite can vary between 30 and 60 wt% Cr 2 O 3. High-Cr chromites (> 46 wt% Cr 2 O ...
