Prediction of Sulfur Removal from Iron Concentrate Using Column
Froth feature extraction plays a significant role in the monitoring and control of the flotation process. Imagebased soft sensors have received a great deal of interest in the flotation process due to their lowcost and nonintrusive properties. This study proposes datadriven soft sensor models based on froth images to predict the key performance indicators of the flotation process. The
