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 Cmeans clustering method is used for flotation

As valuable minerals are soft in comparison to the host rock with a significantly higher solids density they tend to concentrate in the recirculating load of the grinding circuit This can lead to the overgrinding of the valuable minerals until they report to the cyclone overflow which in turn can lead to lower recoveries in the flotation circuit
