density density separator for iron ore

CROSSFLOW SEPARATOR - Eriez Flotation

distribution, separations based on density and shape can be successfulyl achieved. Common applications include removing rock (SG 2.65) from coal (SG 1.35), upgrading iron ore, and the removal of silica from heavy-mineral concentrates. In addition, minerals such as mica can be separated from ores such as phosphate and sand due to its flat shape.
