In particular, the froth application rate heavily affected the overall recovery of the hybrid system as well as the performance of the flotation process. Optimum surfactant usage to generate froth (per liter of treated water) was 0.25 mL/L at approximately 2000 NTU of influent turbidity and 0.015 mL/L at approximately 200 NTU of influent turbidity.

The problem in feldspar flotation is to recover slime free granular products, all minus 20 mesh, usually with not over 10% finer than 200 mesh. Flotation under these conditions is critical and pulps are abrasive as well as corrosive. Action of the feldspar pulp must be counteracted by proper selection of equipment to withstand these conditions.
