CSU Marches into Zambia for Tailings Exploitation
The Central South University inked agreement with Zambia's Ministry of Mining Industry & Mineral Products Exploitation on the morning of June 23 in Changsha, and both sides are to conduct comprehensive collaboration. Maxwell, minister of the Ministry of Mining Industry & Mineral Products of Zambia, Gao Wenbing, secretary of the Party Committee of the Central South University, and Huang Boyun, president of the university, attended the signing ceremony.
As the fourth biggest state in copper production in the world, Zambia's accumulative tailings amounted to several billion tons, causing not only heavy metal pollution but also huge waste containing several million tons of copper. The Central South University takes the lead in biological copper extraction in the world, and its technology in this field can improve the copper extraction rate from the tailings for Zambia by over 30%.
With the technological support of the Central South University, the used-to-be "burden of Zambia" may be transformed into a treasure to safeguard the resource security of China.
According to the agreement, the Central South University will provide technological support to Zambia in terms of fully utilizing the tailings, solving the environmental problems and tapping mineral sources, and cultivate local senior talents for the state.
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
