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.
