Impact Factor of Bacterium Activity and Impact of Leaching Rate Efficiency

Abstract

Abstract: The influence of different concentrations of all kinds of extractant and ferrous ion on the growth and activity of acidophilic microorganisms and copper bioleaching rate were studied during bacteria cultivating and bioleaching.The results show that bacteria numbers and activity are restrained when extractant is added.The copper leaching rate is changed as bacteria activity.The bioleaching rate will be increased on the condition of bacteria activity by adjusting concentration of extractant and ferrous ion in bioleching solution.

Key words: Bioleaching, Bacterium activity, Impact factor, Copper leaching rate
