chromite extracted from ores
Chromite - an overview | ScienceDirect Topics
Mihail I. Gasik, in Handbook of Ferroalloys, 2013 8.2.3 Chromium Ores and Chromites Processing. Chromite ores, as might many others, be mined by open-pit and underground methods. The share of underground mining varies between countries and deposits. The extracted ore is subjected to crushing and sorting (normally rich ore containing more than 45% Cr 2 O 3

Process for extracting chromium from chromium ores ...
Chromium occurs with a valence of three in its naturally occurring 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.

Chromite: The only mineral ore of chromium metal
Chromite can be challenging to identify. Several properties must be considered to differentiate it from other metallic ores. Hand specimen identification of chromite requires a consideration of: color, specific gravity, luster, and a characteristic brown streak. The most important clue to identifying chromite is its association with ultrabasic ...
