Efficient flotation Cell Level Control
Flotation cells are mechanical equipment that bring the ore in contact with air, water, and chemical agents. Their main function is to separate the previously conditioned slurry into a concentrate and tailings. The level of these cells is controlled by dart valves, which in turn are operated by actuators.The calculation of the level control valve (Dart) in flotation cells …
