Mineral size recovery curves in spirals are calculated using data from two iron ore processing plants. • Recovery of iron carrier particles increase up to 0.2 mm and then decreases due to the Bagnold force.. The decrease of recovery for coarse silica carrier particles is more important than that of iron carrier particles.
