Conversion of Chromium Ore Processing Residue to Chrome Steel

Weber (1993) has also demonstrated that the chromite ore cannot be reduced by CO gas alone, in the absence of carbon. The ore can be reduced by carbon, but the reaction may proceed through two steps: FeCrO 4 + 4C Æ Fe + 2Cr + 4 CO 2 and C + CO 2 Æ 2CO. Carbon: the reductant amount / size / type Ding (1997) used graphite bought from Aldrich Chemical. The weight ratio of graphite to

Alluvial Chrome Recovery Peacocke & Simpson

Ore feed to the plant comprises predominantly eluvial soils with a high clay content, and containing between 10 and 20% Cr2O3. Complete dissemination of the clay is required in order to liberate the chromite grains, which lie mostly in the particle range 50-250 microns. Minor ore sources also include competent chromite-hosting rock and a highly “sugary” ore, where loosely-bound chromite

01/06/2014 The reactor was loaded with 75 g chromite ore, 353 g analytical grade KOH (mass ratio of alkali-to-ore is 4:1), and an amount of ultra-pure water. Subsequently, the autoclave was sealed and stirred to keep the slurry suspended during the experiment. The autoclave was placed in the cavity of a heating furnace, heated to the preset reaction temperature, followed by oxygen injection. The oxygen

Leaching of chromite ore in concentrated KOH by catalytic

Key words: chromite ore; copper oxide; leaching; catalytic oxidation 1 Introduction Chromate production from the chromite ore is an important metallurgical process but it is usually associated with gross pollution [1,2]. Nowadays, the alkali roasting method accounts for more than 90% of global chromate production [3]. In the typical alkali roasting method, chromite ore is calcined at about

Ore production. Chromite ore was extracted from open-pit mines reaching depths of approximately 200 meters until 2005. In 2003, underground mining began. The underground mine is accessible either via an incline ramp or a mine shaft. Ore extraction started at level 500, from which the process proceeds upwards towards the bottom of the open-pit. Fully excavated primary stopes are filled with waste rock. From each stope, the ore is carried to an underground crushing station. The crushed ore

Leaching of chromite ore in concentrated KOH by catalytic

Abstract: CuO was used as a catalyst in the concentrated KOH solution to enhance the leaching of chromium from the chromite ore. The impacts of temperature, KOH-to-chromite ore mass ratio, CuO-to-chromite ore mass ratio, and gas flow rate on the chromium leaching rate were investigated. The results indicated that CuO played an important role in improving the chromium leaching rate.

Dissolution and reduction of chromite ore in ferrochromium

at 1650°C under an argon atmosphere. The chromite ore having a particle size range of (-1.0+0.5) mm was fed into the molten slag. The process involved both the dissolution and reduction stages, as the reducible oxide components of the chromite ore were reduced by the carbon of the graphite crucible. The metallic globules of Fe and Cr were seen mostly on

A novel reductive alkali roasting of chromite ores

05/02/2021 Since the S African chromite ore contains more than 14 wt per cent of alumina for every tonne of ore processed, it is estimated that a maximum of 140 kg of alumina may be produced by utilizing ∼60.4 kg of CO 2 produced from the burnt CO gas. Based on the mass of recoverable alumina, the corresponding mass of CO 2 likely to be sequestrated via the production alumina is less than 8%. The
