Abstract:

Electric and electronic wastes are one of the important problems of environmental pollution in modern times, this paper introduces research progress of biological metallurgical technology in extracting metals from ores and electric and electronic wastes at home and abroad.The traditional pyrometallurgy and metallurgical technology have low recovery rate,complex recovery process,high energy consumption,causing water pollution.In comparison, biological metallurgy technology is a method of extracting metals from solid mineral to the solution by metabolism of microorganisms.It can be used for extracting metals from the low grade of ore and electric and electronic waste, meeting the current win-win economic and environmental requirements of the times due to advantages of low cost, high recovery efficiency,low energy consumption,non-toxic and harmless,environment friendly,etc.Today,more and more attention are paid to the environmental protection,using biological technology to extract the metals from electric and electronic waste is one of the environmental technology with great potential.

Key words: Biological metallurgy technology, Ore, Electric and electronic wastes, Metal
