Ltd (CNMC). The company operates a copper concentrator and hydrometallurgical complex in Kalulushi District.

The total storage capacity of the combined TD15G-1 facility will be 5.48 million m³ (effective capacity 4.76 million m³) and cover an area of 0.47km2. The TSF will be a 22.5 m fully engineered tailings dam lined with a 1.5 mm HDPE composite geomembrane anti-seepage layer. Tailings from the existing leaching plant will be pumped via a dedicated HDPE pipeline of approximately 0.225 m diameter. To manage any potential seepage that may bypass the liner through construction defects or damage, the following systems will be in place: The estimated lifespan of the proposed project is expected to be 10 years.
