【摘要】 针对铜精矿物相组成分析耗时滞后和在线准确判断实现困难的问题,依据地球化学和成矿动力学理论,提出铜精矿历经漫长成矿过程后已基本达到或接近平衡态的假设,并将铜精矿视为若干化合物的混合体,基于成矿平衡态铜精矿体系吉布斯自由能最小原理,构建了铜精矿物相组成线性规划计算模型。几种典型铜精矿的实例验证表明,该模型能较为准确地计算铜精矿物相组成。更多还原

【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.更多还原
