The tertiary crushing station is usually based on cone crushers or vertical shaft impact crushers. The fragmented ore product from the crushing plant is thereafter reduced in very smaller particles say, from 0–12 mm down to the range of 50–100 μ m, in milling/grinding circuits by grinding machines to allow mineral recovery process [18].
