[ 1 ] - EFFECTOFTHE TYPE OFCARBON MATERIALON THE REDUCTION KINETICS OFBARIUM SULFATE
Abstract: the reduction agent. Pellets of barite ore containing about 95% BaSOtemperature, time, ore grain size and the type and grain size of the carbon materials. Graphite, coke and charcoal havebeen used as the reducing agent and the reduction experiments have been performed in the temperature range of 925-1150 °C. Apart from conducting the experiments using pellets made of ore powder, kinet...
[ 2 ] - EFFECT OF MECHANICAL ACTIVATION ON THE KINETICS OF LEACHINGOFCHALCOPYRITE IN THE FERRIC SULFATE MEDIA
Abstract: has been investigated. It has been shown that the mechanism of leaching reaction is diffusion through the product layerand does not undergo any change as a result of mechanical activation in a wide range of experimental conditions.Leaching rate is strongly influenced by milling intensity and the effect of ball to powder mass ratio is stronger thanmilling time. Curve fitting of experim...
