and precious metal resources[J]. China Metal Bulletin, 2010(45): 17-19. [2] GRAEDEL T E, BERTRAM M, FUSE K, GORDON R B, LIFSET R, RECHBERGER H, SPATARI S. The contemporary European copper cycle... for more than 90% of the total slag loss. The precious metal multiphase equilibrium model was modified with a mechanical suspension rate. The modified model was used to calculate the Au and Ag contents......

potentials of adsorption metal ions [2], noble metal ions [3-5], dyes [6-7], proteins [8] and humic acid [9-10]. Several methods have been used to modify raw chitosan flake by either physical or chemical... for metal ions because of the synergistic effect of high relative molecular mass. Today, metal contamination of various water resources is great concern because of the toxic effect on the human beings......
]. The research indicated that the cathode material of LiMn2O4 doped with some certain metal ions had better cycle performance, and yet the specific capacity of this cathode material was reduced. While some anions, such as F-, when doped into such material, could enhance its specific capacity, but could hardly improve the cycle performance[14,15]. In this paper, the author selected metal ions combined......
