commonly used beneficiation methods for iron ores are the gravity and magnetic separation techniques [4−6]. Gravity separation is widely used in mineral bene-fication practices for its low-cost, ease of operation and easy to control, and eco-friendly nature [4, 7−9]. It is an appropriate method of concentration for size
