For sulfide ores, on the other hand, selective flotation normally follows the crushing and grinding stage and requires an optimal degree of liberation. In the flotation process, the finely ground ore, mixed with water and special reagents, is agitated by mechanical and pneumatic devices. These produce air bubbles in the ore water mixture, or
