TD6 - Chambishi (NFCA CNMC) - Zambian Copperbelt (sitios de interés)
Descripción del sitio
Tailings Dam 6 is a pollution control facility used to clarify effluent from both the NFCA and Chambishi Metals plc operations. The effluent is transported from the NFCA mine site and the Chambishi Metals plc site via a series of open drains that empty into one main canal leading to the TD 6 inlet.
Originally, the Chambishi stream, which ran through the Chambishi Mine site, was diverted so that it would carry effluent from the mine site to TD 6. In case of floods, provision has been made to bypass flood flows so that only part of the discharge is diverted onto the dump whilst the remainder is routed in a channel around the dump to rejoin the diverted Chambishi stream at the TD 6 decant outlet. Effluent from the TD 6 outlet is discharged to the New Dam, which in turn discharges into the Chambishi stream.
