Chromite Ore - an overview ScienceDirect Topics

Chromite ore is usually a combination of spinels with associated minerals such as calcite, magnetite, talc, serpentines and uvarovite. Chromites crystals exhibit an octahedral structure similar to magnetite. The Cr 3+ ions are in the octahedral position with oxygen. The chromium rich phase is antiferromagnetic.

Chromium Ore - an overview ScienceDirect Topics

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].
