Abstract

Abstract

A mathem aticalmodel for heap bioleaching was developed to analyze heat transfer,oxygen flow,targetions distribution and oxidation leaching rate in the heap,and the model equations were solved by Comsol Multiphysics software.The numerical simulation results show:the concentration of oxygen is comparatively higher along the boundary of the slope,and lower in the center part where leaching rate is slow;the temperature is comparatively low along the slope and the highest along the bottom region near the slope,and the difference is more than 6℃;the concentration of target mentalions is highest in the bottom region near the slope;the oxidation leaching rate is bigger in the bottom and slope part with quicker reaction rate,and comparatively smaller in the restpart with lower oxygen concen tration.
