Cr(VI) generation during sample preparation of solid

Chromite ore Metallurgical-grade chromite ore samples ( 1 mm) were col-lected during a sampling campaign at the Xstrata Thorncliffe Mine in the Mpumalanga Province of South Africa. This mine is situated on the eastern limb of the Bushveld Complex, near the towns of Lydenburg, Steelpoort and Burgersfort (Howat, 1994).

Chromite Mineral Information and Facts Chrome Ore

It is usually nonmagnetic, but some specimens show slight magnetism because of the admixture of magnetite with chromite. Industrial Uses of Chromite Chromite is the sole source of the metal chromium, which is the chrome-iron alloy employed in the manufacture of special grades of steel.

Chromite separation GUT

The amalgamation of chromite sand and silica sand, which arises inevitably at the shake-out station, may lead to quality problems of the casting, in case of reuse of the reclaimed sand. With G U T plants chrome ore sand can be separated sorted from silica sand and can easily be re-used in the sand circuit for cores and moulds.

Reducing energy consumption by alternative processing

The carbothermic reduction of chromite ore to produce high carbon ferrochromium is among the most energy intensive metal extraction processes performed, due not only to the highly endothermic nature of the reduction reactions but also the very high operating temperatures required for the smelting operation to separate the chrome-containing alloy from the discard slag.
