Prediction of dissolution of copper from a chalcopyrite carbonatite ore of South Africa
Chalcopyrite accounts for 70% of all copper bearing minerals and therefore has been studied closely to understand the dissolution kinetics in hope of overcoming the passivation film and increasing the extraction rates ...
Effect of fine coal tailing porosity on the mobility and speciation of heavy metals in the leachates
The effect of porosity of coal tailings on the mobilization and speciation of heavy metals is important for the implementation of management strategies. In this study, column leaching experiments were carried out to ...
