Canonical correlation analysis based process operating performance assessment and its application to a gold hydrometallurgy process

Process operating performance assessment judges the optimal degree of the production online. The assessment result guides the production to achieve the maximal benefit. Hence, the study on operating performance assessment is of great significance. To extract the most correlations between the process variables and the assessment indices, an operating performance assessment method based on canonical correlation analysis is developed in this research. Accordingly, an effective assessment strategy is established. The proposed approach assesses the optimal degree of process performance online with high accuracy. Finally, the approach is applied to a gold hydrometallurgy process, and the feasibility and validity is illustrated.
