本文介绍影响铅、锌浮选回收率的主要因素,回归分析所揭示的这些因素与铅、锌回收率之间存在的相关关系。并介绍利用所确定的一元线性回归方程对铅、锌浮选生产过程进行的预测和控制。以及在多因素生产过程中回归分析工作有待深化的方向。 This article introduces the main factors that affect the recovery rate of lead and zinc flotation, the correlation analysis between these factors and lead and zinc recovery revealed by regression analysis. The prediction and control of the production process of lead and zinc flotation using the determined linear regression equation are also introduced. As well as the direction of regression analysis to be deepened in the process of multi-factor production.
