Flotation Plant (ChambishiCopperMine NFCA CNMC) - Zambian Copperbelt (sitios de interés)
Descripción del sitio
3.2.1.7 Production CapacityThe NFCA concentrator at Chambishi Mine was designed to crush 6,500 tons of ore per day, mill 6,500 tons of ore per day and concentrate 379 tons of copper concentrates per day with a grade of 40%. The concentrator's production recovery is 95.5%. However, the plant is currently operating at half capacity because only about3,500 tons of ore per day are received from the underground operations. The copper concentrate production output is anticipated to improve with increasing ore output from the underground operations.
3.3 Potential Future Developments at Chambishi Mine
NFCA is committed to increasing its investment in Zambia by widening its scope of mineral development. The company intends to undertake the following developments in the future:
Extension of the underground mining rights area to cover a 100 km2 area;
· Increasing mining and processing rates;
· Development of the Chambishi west ore body;
· Development of the Footwall reserves;
· Construction of a sulphuric acid plant;
· Construction of a leach plant for reclamation of copper from low-grade ore;
· Construction of a smelter.
With regard to the reclamation of copper from low-grade ore, it is envisaged that copper will be reclaimed as follows:
Low grade oxide ore from ore stock piles No.'s 3 and 4 will be reclaimed by a process involving heap leaching, solvent extraction, and electro-winning;
· Fine oxide ore from tailings dams No.'s 7, 7A, 8, 9, and 15 will be reclaimed by a process involving agitation, solvent extraction and electro-winning; and
· A process involving heap leaching, solvent extraction and electro-winning will reclaim vat leach tank residue from tailings dam No. 10.
