TECHNICAL EVALUATION OF REAGENT DOSING PUMPING SYSTEMS IN FLOTATION CIRCUITS
Vale's ore processing plants use different types of pumping circuits for flotation reagent dosing. Most commonly, circuits with centrifugal pumps, diaphragm pumps, and peristaltic pumps are used. Alternative arrangements can also be used, such as helical pumps and direct dosing from reagent sto...
