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.

Dissolution and reduction of chromite ore in

2018-12-26 · chromite ore was fed into the molten slag, and was followed by reduction of iron and chromium oxides. Due to the fact that the chromite ore was fed in granular form, as expected, a greater contact area was created which influenced the dissolution / reduction reaction between the ore and the slag. The slag composition played a significant role ...
