The Research of the Flotation Recovery Prediction Methods Based on Advanced LS-SVM

摘要

Flotation recovery is an important index of flotation process, in order to change the existing detection methods of low accuracy，a soft measurement model of flotation recoveries is proposed based on improved weighted LS -SVM. According to the flotation foam characteristics and the corresponding relation of flotation recovery, the fuzzy C-means clustering method is used for flotation characteristics of data processing, the image characteristic values as prediction model input and using genetic algorithm to optimize the parameters of the model. The result show that the modified algorithm can overcome a prediction standard model LS -SVM algorithm parameter optimization shortage, and have better forecasting effect which provide effective protection for flotation process operation and flotation operation stable operation optimization .
