KCM to set up leach plant
KONKOLA Copper Mines (KCM) intends to develop the proposed agitated leach plant at Nchanga Mine to process refractory ore materials to produce 50,000 tonnes per annum of finished copper at a cost of US$172 million.
The project with a life span of 13 year is expected to create 700 direct and 1,000 indirect jobs. After construction, 300 permanent jobs will be created for locals.
KCM is part of the global Vedanta Resources Plc, which acquired KCM assets in 2004, including Nchanga Mine, in Chingola.
According to the environmental impact statement (EIS) submitted by KCM to the Environmental Council of Zambia (ECZ) KCM says among copper-bearing ores produced at Nchanga mine are refractory ores which are difficult to treat using conventional copper ore-treatment methods hence their branding as CRO.
About 156 million tonnes of these Chingola Refractory Ores materials have been mined and stockpiled at various locations within Nchanga Mine Licence Area (MLA).
It says the project process will involve crushing, milling and washing treatment of CRO material. The process uses acidic solutions to treat the materials into finished copper.
The company says if approved, the proposed project life will be at least 13 years although the number of years is likely to increase if more CRO materials are discovered and brought for treatment at the proposed plant, adding that approximately US$172 million will be spent on this project.
It says unemployment in Chingola is a challenge because of the employment absorptive capacity of industry which has remained stagnant.
The global financial meltdown and recession contributed to a significant reduction of business with the mines and subsequently job losses.
Positive impacts of the proposed project include guaranteed jobs, increased employment opportunities, poverty reduction, and increased social and family cohesion through trickle-down effects.
Other positive impacts include availability of assets as scrap post-closure, more money for sharing, including for corporate social responsibility, growth of small-scale sector and improved occupational health and safety.
The downside of the proposed project includes loss of income and social disruption, post-construction and closure, mining dependence, pressure on social services due to immigration, pollution and land degradation effects, potential liability and cut-off of informal mining sector although mitigation measures have been put in place.
