氰化贫液除杂的必要性及其综合评估

以三山岛金矿新立氰化厂生产状况为依据，以直接影响生产流程中氰化钠消耗量的杂元素Cu 含量这两因素建立了一元线性回归模型，在近8 年的流程Cu含量与氰化钠消耗数据分析的基础上，预测了今后的氰化流程中铜及氰化钠用量的趋势，提出了氰化贫液处理项目的必要性，并在综合考虑氰化贫液除杂各种流程的特点的前提上，提出了酸碱二段沉淀（MNR）污水处理工艺，通过实践与分析，对该氰化贫液除杂工艺效果进行了综合评估与项目展望。

Necessity and Comprehensive Assessment of Lean Solution Processing Project

We establish a linear regression model on the base of two factors：cyanide plant production status and copper content,the direct impact of sodium cyanide consumption.According to the data analysis of copper content and sodium cyanide consumption for recent years,we forecast the trend of copper cyanide and sodium cyanide consumption in the future.After the premise of considering a variety of cyanide impurities flow characteristics,we finally put forward erduan acid precipitation（MNR） sewage treatment process.At the same time,through analysis and practice of the process,we also propose the necessity of the project of handling cyanide lean solution.
