The flotation separation process mainly includes: (1) Grind the ore finely by the ball mill or rod mill to dissociate useful minerals from gangue minerals. (2) Separate the ore by the flotation machine. Adjust the ore pulp and add flotation reagents. (3) Do the flotation processing. (4) Filter, concentrate or dry the product.
