To perform a flotation process the mineral is finely ground (particle sizes between 50 and 150 μm), then the ground mineral is mixed with water in a container called a flotation cell. Afterward it is introduced into the flotation cell via an external medium and small bubbles of air produce a pulp (metallurgical pulp) where mainly particles, water, and air coexist.
