根据铜矿物各相的浸取特性,利用铜各相态稳定的浸取率常数建立数学模型,用目标约束遗传算法(GA)对一次性浸取测得的浸取总量进行计算,求得铜各相态的含量。该方法简便快速,缩短了传统相态分析的流程,避免了串相问题,为相态分析提出了一种新方法。相对标准偏差(％)为:自由氧化铜相1.46,结合氧化铜相17.59,次生硫化钢相1.86,原生硫化铜相2.73,总铜0.803。
According to the leaching characteristics of each phase of copper minerals, a mathematical model was established based on the steady-state leaching rate constants of copper, and the total leaching amount measured by one-time leaching was calculated by using the target constrained genetic algorithm (GA). Copper content in each phase. The method is simple and fast, shortens the traditional phase analysis process, avoids the problem of series phase, and proposes a new method for phase analysis. The relative standard deviation (%) was 1.46 for free copper oxide phase, 17.59 for copper oxide phase, 1.86 for secondary sulphided steel phase, 2.73 for primary copper sulphide and 0.803 for total copper.
