采用随机理论的统计方法 ,分析了难处理金矿常温常压强化碱浸预处理的砷转化过程 ,给出了转化主方程 ,用母函数方法解出了主方程的近似解。在远离临界点的非平衡状态下 ,得到了与实测值吻合较好的统计结果 ,为建立难处理金矿砷转化率与时间关系的数学模型 ,并进而为预测一定预处理时间下的金的氰化浸出率 ,奠定了一定的基础 Based on the stochastic theory, the arsenic conversion process of alkali pretreatment at normal temperature and pressure in refractory gold mine is analyzed. The main equation of conversion is given, and the approximate solution of the main equation is solved by the method of principal function. In the non-equilibrium state far away from the critical point, the statistical results agree well with the measured values. In order to establish the mathematic model of the difficulty in dealing with the conversion rate of arsenic in the gold mine and the time, and then to predict the gold under certain pretreatment time Cyanide leaching rate, laid a certain foundation
