Biohydrometallurgy: The Key To Unlock Mineral Resources Value

The status of utilization of copper ore resources, and the application and development of biohydrometallury technology in the world is reviewed. Based on the characterization of Zambia?s copper resources, biohydrometallurgy technology is shown to be a practical approach to extract and utilize the enormous low grade copper resource, such as ore tailings and low grade copper ore in this country. Through the cooperation of CSU, China and MMMD, Zambia, ?CNMC-CSU Demonstration Base of Biohydrometallurgy Technology in Zambia? was launched and several biohydrometallurgy plants are being constructed. This indicates that the biohdyrometallurgy technology would be applied soon in Zambia and in the whole Africa. Biohydrometallurgy technology stands as an efficient alternative to the traditional pyrometallurgy process and it can be the key to unlock mineral resources value.
