A mathematical model for enargite bioleaching at 70℃by Sulfolobus BC in shake-flasks has been con-structed.The model included(1)the indirect leaching by-Fe3+and Fe3+regeneration by suspended Sulfolobus,and (2)the direct leaching by the attached Sulfolobus.The model parameters were optimized using genetic algorithm (GA).Simulations of the ferric leaching.,and bioleaching processes were done using this model The dynamic changes of the concentrations of Cu2+,As3+,As5+,Fe3+and/or Fe2+,as well as ferric-arsenate precipitation were ac-curately predicted.
