    ABSTRACT Cationic reverse flotation of quartz is the standard or reference concentration route for itabirites containing at least 45% iron. Preceding the flotation stage, desliming in hydrocyclones must be conducted to remove ultrafine and colloidal particles from the flotation feed. The flotation performance assessed by weight and metallurgical recoveries and silica contamination in the
