Mineralogical observation made during the kinetic dissolution study of chalcopyrite mineral in sulphate media under free pH at room temperature
Nyembwe, Kolela J.; Fosso-Kankeu, Elvis; Waanders, Frans; Malenga, Edward Ntumba (EARET, 2018)An attempt to determine the various phenomena at play and leaching mechanism of chalcopyrite dissolution, was conducted on a chalcopyrite concentrate. The study was performed at atmospheric conditions (room temperature) ... -
Prediction of dissolution of copper from a chalcopyrite carbonatite ore of South Africa
Barlow, Brad; Fosso-Kankeu, Elvis; Nyembwe, Kolela; Waanders, Frans; Malenga, Edward Ntumba (EARET, 2018)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 ...
