A study has been made of the electrochemical behaviour of carrollite and chalcopyrite in the presence of xanthate and cyanide in aqueous solution. The investigations involved measurements of rest potentials and cyclic voltammetry of the sulphide minerals understudy. The results showed that the...

The study was aimed at contributing to the provision of good quality groundwater supply in Petauke District. It comprised collection and analysis of 50 groundwater samples from boreholes in the dry and wet season in Petauke Town. Water exit points were sterilised before collection of samples....

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 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...

Evapotranspiration (ET) is a dominant hydrologic flux in the water budget of semi-arid areas.Thus, accurate estimation of its dynamics in such environments is critical for improvingN water resources management. In this study the physically-based Surface Energy Balance System (SEBS) model was...

The objective of this research was to characterise the rockmass to determine appropriate support system for the decline with the 4.5m height and 4m wide in highly aquifer strata, recharging the water flow of 18, 000 cubic meters per day. As a result production targets reduced due to excessive...

Water is a scarce and a vulnerable resource. The use of water in an environmentally sustainable manner can help achieve global development. This is because an environment with poor water quality is bound to encounter catastrophic problems and subsequently derail global development. 'Shared water...

In the Chisamba area, some lithologies hitherto mapped as quartzites and dolomitic marbles are quartz mylonites and interbanded calc-silicate, marble and amphibolites, respectively. Both meso-and microstructural fabrics in the Chisamba area indicate that deformation associated with shearing was...

The syenites and quartz feldspar porphyries of the Mumbwa district occur as satellite bodies at the north east margin of the Hook Granite Massif, a large batholith dated 456 Ma, and intrude the pre-Cambrian Katanga metasediments. The composition of syenitic rocks varies from hornblende biotite...
