Studies done on Mimbula ore have been on agitation leaching, high temperature and pressure leaching and treatment of refractory ore (TORCO) process. However these methods attracted significantly high capital investment leaving heap leaching as a more economically attractive method to be...

Release analyses were done on the Chingola Refractory Ores (CRO), which is a mixture of refractory oxides and sulphide copper minerals with an average grade of 1.37% total copper (TCu) with the goal of optimising the froth flotation process of Chingola Refractory Ores. Cupriferous mica,...

The initial work of this project involved determining the optimum mesh of grind and frother dosage for Lumwana and Kansanshi ores. This work was conducted at the University of Zambia mineral dressing laboratories based at School of Mines. Further work involved carrying out surface tension, bubble...
