Dissolution of chromite in slags
Mineral Processing and Extractive Metallurgy, 2013AbstractThe dissolution of chromite from Bushveld Complex of South Africa in liquid slags was studied experimentally. The slag compositions chosen were representative of ferrochromium production and stainless steel making. The dissolution process was monitored by chemical analysis of samples taken from the melt at predetermined time intervals and SEM ...

Minerals Engineering, 1994
Abstract The kinetics of the chemically controlled reaction between chromite and sulphuric acid, to form chromium(III) sulphate has been studied in the temperature range 140° – 210°C. The effect of temperature, sulphuric acid concentration and perchloric acid addition on the rate of dissolution of chromium has been studied.

Ruthenium in komatiitic chromite
Geochimica et Cosmochimica Acta, 2011Abstract The distinction between Ru in solid solution and Ru-bearing inclusions is essential for the predictive modeling of platinum-group element (PGE) geochemistry in applications such as the lithogeochemical exploration for magmatic sulfide deposits in komatiites.

Kinetics of chlorination of chromite
1998Chlorination can be an efficient alternative for the physical beneficiation of refractory metals' bearing materials. The chlorination of a chromite mineral was studied up to 1050 °C using thermogravimetric analysis. The effects of the gas flow rate, temperature and partial pressure of the reactive gases on the reaction rate were studied in isothermal ...
