| Abstract: |
| Solute transportation is one of the most important processes during bioleaching.The transportation of leachate,reaction products and nutriment between solid phase,liquid phase and gas phase is the phase transportation,which is the main from of solute transportation.O2 and CO2,which are required for chemical reaction and growth of bacteria,are provided by dissolution and diffusion of the air.The absorbing of the bacteria can be divided into two stages,primary absorbing and secondary absorbing.Result of the s... |
