Large quantities of old copper smelting slag containing cobalt exist at Nkana Division of Zambia Consolidated Copper Mines. Recovery of cobalt from the slag would contribute significantly to the economy of Zambia. A literature review, however, indicated that although processes have been developed...

Rock slope stability is a very important research area for many geo-engineers concerned with civil or mining works. Slope stability of pits, roads, tailings dams and other embankments is very cardinal as it directly impacts on the working or utilisation of these facilities. The Nchanga Open Pit...

The rapid population growth of Lusaka has brought adverse effects on water supply and sewage treatment facilities in the District. Consequently, authorities in Lusaka have allowed use of septic tanks and boreholes in the same area in some Townships. St. Bonaventure located about 7km from Town...

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...

A study was conducted to determine the net carbon sequestration potential of citrus to mitigate climate change. Perennial crops such as citrus have the potential to absorb and sequester carbon dioxide from the atmosphere, save for the carbon released back through the application of agro-chemical...
