Chromium Ore. Chromium ores are often classified based on their elemental composition and industrial use into: high-chromium (46–55% Cr2O3, Cr:Fe >2.1) used for metallurgical processes, high-iron (40–46% Cr2O3, Cr:Fe 1.5–2.1) used for chemical and metallurgical purposes, and high-aluminum (33–38% Cr2O3, 22–34% Al2O3) used widely as refractory material [1].
Chromium processing, preparation of the ore for use in various products. Chromium (Cr) is a brilliant, hard, refractory metal that melts at 1,857 °C (3,375 °F) and boils at 2,672 °C (4,842 °F). In the pure state it is resistant to ordinary corrosion, resulting in its application as an electroplated
Chromium. 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.
