TD19 Musakashi / Chambishi (NFCA CNMC) - Zambian Copperbelt (sitios de interés)
Descripción del sitio
The Musakashi Tailings Dam (TD 19) is an active, classified dump situated about 10 km north of the Plant Area. It consists of an earthfill embankment which was 360 m long and 15.5 m high
since 1996. The dam is due to be extended in two phases, so as to increase its tailings containment capacity. During the first phase, which is on-going, the embankment wall is being extended to 700 m long, and to 21.5 m high. During the second phase of extension the dam, the height of the dam will be extended by a further 4 metres to 25.5 metres. The crest width is 3m. The TD was originally designed to have a capacity of 5.7 million tonnes, but provisions were made to raise the embankment to increase storage capacity to 23 million tonnes of material. The tailings dam receives tailings from the concentrator at the NFCA mine site, and the tailings are transported to the dam through a refurbished tailings pipeline
