| Abstract: |
| To address analysis time lag and inaccurate online judge for phase compositions of copper concentrate, based on Geochemistry and metallogenic dynamics theory, the assumption that copper concentrate had been basically under or close to equilibrium state after a long process of mineralization was put forward with copper concentrate regarded as a mixture of several compound. Linear programming model for calculating phase compositions of copper concentrate was constructed based on minimization of Gibbs Free Energy of copper concentrate under metallogenic equilibrium state. Examples of several typical copper concentrates show that the model can be used to accurately calculate phase compositions of copper concentrate. |
