upgrading low grade iron rich chrome ores

ores containing antimony castersmilieu.be

The volatilisation and oxidation of antimony trisulphide have been studied in detail. From the results it is suggested that rich or concentrated ores which do not contain precious metals, arsenic or lead should be roasted to antimony tetroxide, while poorer ores, and ores containing precious metals, should be roasted to antimony trioxide.

WO1990004656A1 Refining of ilmenite by removal of excess

The presence of chromite in significant amount in ilmenite downgrades the market value of the ilmenite. A substantial amount of the chromite may be removed, firstly by a reduction step, secondly by a leaching, aeration or oxidation roasting step and finally by a physical separation step. An optional preoxidation may precede the reduction step and an optional physical separation step may be
