The flotation cell level is used to control the flotation index. During the flotation process, the grade of the concentrate foam is the highest, and the lower the grade, the lower the grade. Thus, when the level of the flotation tank increases, the amount of foam scraping increases, the recovery rate is high, but the concentrate grade decreases. . The grade of tailings also declined. Therefore, the flotation index can be controlled by adjusting the level of the flotation tank. Figure 5-4-11 shows a flow chart for controlling the tailings grade using the flotation cell level. In the system, the feedback control is used to compare the tailings grade measured by the X-ray analyzer with the given tailings grade, and the difference is calculated according to the algorithm I to calculate the required tank level change, and control the tailings discharge. Valves to maintain liquid level stability and required tailings grade. Here, if the tailing grade parameter and the corresponding algorithm I are replaced by the concentrate grade, the system can also realize the concentrate grade control.

The detection of the level of the flotation tank is mostly carried out by a float type liquid level gauge or a blown liquid level gauge. The surface of the buoy is coated with paint and placed in a cylinder to reduce the influence of fluctuations in the liquid level in the tank on the buoy. It is preferable to have a water spray cleaning device.
Carbon Steel Plate is a kind of steel with a carbon content of less than 2.11% and no deliberate addition of metal elements. It can also be called ordinary carbon steel or carbon steel. In addition to carbon, there are also a small amount of silicon, manganese, sulfur, phosphorus and other elements inside. The higher the carbon content, the better the hardness and strength, but the plasticity will be worse. "
