چکیده:

The effect of mineral paricle size on the copper bioleaching by Acidithiobacilus have been studied.Increasing the particle size from 0.15 mm to 3.4 mm enhanced the copper recovery from 51% to 93%. While the copper recovery of finely ground particles (<0.15 mm) was76 %. Also increasing the particle size between 3.4-6 mm adversely influenced the activity of bacteria and copper recovery of this fraction was70 %.
