Pyrolysis Treatment of Chromite Ore Processing Residue by .

Feb 10, 2016 . The pyrolysis treatment with biomass is a promising technology for the remediation of chromite-ore-processing residue (COPR). However, the mechanism of this process is still unclear. In this study, the behavior of pyrolysis reduction of Cr(VI) by cellulose, the main component of biomass, was elucidated.

Processing of chromite ultra-fines in a water only cyclone .

Chromite ore beneficiation is majorly dominated by gravity concentration techniques. In India, about 50% (by weight) of the feed is discarded into the tailing stream during beneficiation process which consists of a huge quantity of the chromite values in fine and ultra-fine sizes. Being strategically important and from the.

Advances towards a Clean Hydrometallurgical Process for Chromite

Jan 28, 2016 . Abstract: Because of the acute toxicity of Cr(VI)-bearing substances, the pollution problem caused by chromite process residue has become a worldwide concern. In the view of relevant studies, the technologies based on the alkali treatment cannot fundamentally resolve the pollution problem, because the.

Discover chrome - Ore Processing

Initial processing of chromite ores can be by hand sorting of lumpy ores, and by heavy media or gravity separation of finer ores, to remove gangue or waste materials and produce upgraded ores or concentrates. Magnetic separation and froth flotation techniques have also been applied in some cases. Most of the world's.

Samancor Chrome Mines - Mining Technology

"Innovations introduced by Samancor have included direct chromite reduction and DC smelting." Bushveld chromite is conveniently milled to recover a fine concentrate by gravity and elutriation techniques. However, ferrochrome furnaces need a porous charge so lumpy ore and chips must also.

Chromite Beneficiation Process - 911 Metallurgist

Mar 19, 2017 . The Problem with Chromite Processing. Experience indicates that chrome ores are concentrated to best advantage by gravity methods. Since recoveries are generally very poor in the fine sizes, the gravity flowsheet must be designed to remove the chrome as soon as liberated by crushing and grinding.
