:: Chambishi Smelter to Expand Operations
Chambishi Copper Smelter (CCS) has proposed to expand its operations aimed to increase production capacity from the current 150,000 tonnes of blister copper to 250,000 tonnes per year.
Some of the intended objectives of the smelter expansion project include the lowering of the cost of production in light of the reduced metal prices and reduction on the amount of the effluent released to the natural environment outside the smelter.
According to the Environmental Impact Statement submitted to the Environmental Council of Zambia, CCS intends to improve on the copper recovery rate so that it could reach 98 per cent and to improve the sulphur dioxide recovery rate to 95 per cent.
“In order to achieve the objectives, CCS will undertake the following activities such as expanding the concentrates shed, extending of the building for the furnace to accommodate the anode furnace and the converter and construction of the additional acid plant and oxygen plant units," stated CCS. “Construction of the concentrator unit comprising of slag cooling system, crusher, milling plant and floatation circuits and construction of the leach plant and modification of auxiliary facilities."
