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...

The Nchanga and Konkola ores have substantial amounts of cobalt in the form of Carrollite (CUC02S4) and Cobaltiferous pyrite ((Co,Fe),S2). These minerals are found in association with copper minerals such as chalcopyrite (CuFeSz), Bomite (CusFeS4) and Chalcocite (CujS). However, the recoveries of...

The erosion of Tuyeres in Refining has been studied in a Physical Model to establish the dependence upon injection conditions such as gas momentum and orifice profile.The erosion phenomena in terms of Mass transfer-mechanisms has also been studied.A coefficient of Mass transfer kc< , has been...

Tine cyanidation process for extracting precious metals (gold and silver) from the anode slimes was investigated. The recovery of these metals from cyanidation solution by adsorption on activated cai-bon has been studied. Ttiis was to assess the cyanidation and adsorption process as a potential...

The reduction of Masuku Cassiterite gravity concentrate by charcoal was investigated in the temperature range of 850 to 1100oC. A combination of sample weight loss measurements, exist gas analysis and chemical analysis of the reaction products was used to monitor the course of the reaction.The...

Kaluwe phosphate ore constitutes calcite(74.4 wt %)as the major mineral with minor amounts of apatite(5.9 wt %),opaques(13.5 wt%),which are predominantly iron minerals,quart/feldspar(5.7) and traces of biotite(o.5 wt %).The chemical composition of the ore averaged 2.2% p2o5,47.7% Cao,1.6%mgo,1.2%...
