The plant has a capacity of 1,000 m3/h, and has been operating since early 2008. In 2011, a Met-IXTM plant was built downstream of the ChemSulphide® plant to treat a 800 m3/h slipstream to recover nickel and cobalt.
BioteQ’s water treatment processes deliver lower life cycle costs for water treatment, and enhance environmental performance at the Dexing site. For example, in the past three years, the Dexing plant has treated on average 7.4 million m3 of water and removed about 1.8 million pounds of copper annually from the environment. The plant generates an operating profit for the joint venture, ensuring that the water treatment plant is both economically and environmentally sustainable.
Construction of the plant improved overall site water management and protected an important wetland from heavy metal pollution. BioteQ has also assisted the owner with the design and operation of two high density sludge lime plants on the large site.
The Dexing water treatment plant won the 2008 China Mining Environmental Protection Award, recognizing BioteQ’s sustainable technology and Jiangxi Copper Company’s leadership in protecting and preserving the environment.
The application of BioteQ’s technology at the Dexing Mine has economic and environmental benefits. The plant:
