Kinetic Study Of The Bioleaching Process Of Miduk Copper Sulphide Minerals By Modeling

Bioleaching method makes use of bacteria in solving metallic sulphides, so that these bacteria tend to convert insoluble metal sulphides into soluble sulphates. Since the kinetics description of this process is inevitable for better interpretation of relation between metabolism and growth of live organisms, as well as optimization of metals extraction processes, in this paper, this description is represented and designed in mathematic (kinetics) model for copper sulphide minerals based on Monod kinetics model. According to this model, special growth rate of bacteria (?) is a hyperbola function of restrictive substrate concentration (S). By Solving and developing of Monod kinetics model, a comprehensive kinetics model for bioleaching of copper sulphide minerals results. The designed is also applicable for other metal sulphides.
