Nchanga Open Pit (NOP) is facing a critical equipment planning decision after undertaking improvement projects at the processing plant namely Elevated Temperature Leaching, Heap Leaching and Cobalt/Copper separation. Elevated Temperature Leaching has resulted in 20% increase in the recovery of...

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,...

Konkola Copper Mines’ (KCM) Nchanga smelter utilises a modern technology of direct to blister flash smelting process designed by Outotec, Finland. Slags from the direct to blister flash smelting unit are carbothermically reduced through a two stage electric slag cleaning furnaces (ESCF) to...

This study assessed surface water availability in Solwezi River basin in Northwestern Province of Zambia. The main objective was to quantify various components of the water balance to ascertain surface water availability in Solwezi River Basin in view of the increasing water demand. Climate data...

This study embarked on trend analysis to understand the relationship that exists in weather, precipitation and river flow using time series data. The study area was the entire country of Zambia. Secondary hydrological and weather data used was representative of the six catchment areas of the...

There has been a lot of outcry from the public that Zambia’s mineral tax reforms, with an aim to optimize revenue benefits from the mines, have not yielded the desired results. This has mainly been attributed to the weak design of its legislated mineral taxation systems. Due to this underlying...

The focus of the study was to establish factors which influence sustainability of boreholes managed by communities in Chadiza District. In order to do that, the study intended to answer three research questions which are: (i) How does community participation at the initial stage of the borehole...

It is well known that water is a natural resource without which all living things cannot exist. It is a natural requirement for all living things to have access to water, if they have to be alive. It is why seventy percent of our planet earth is covered by water, though the world population is...

Temperatures and humidity at Mindola Sub-Vertical (MSV) shaft have been rising with depth as mining of lower lying copper reserves is achieved. This rise in temperature has been catalysed by a number factors notably the increase of diesel equipment, geothermal gradient (increase in depth), auto...

This study focuses on the spatial and temporal variability of various carbon fractions and fluxes in relation to major biogeochemical parameters in the Zambezi River in Zambia and its major tributary, the Kafue River. Concentrations and composition of stable isotopes of dissolved organic carbon,...
