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...
