Rare earth extraction process control method based on ion characteristic color detection

In the process of rare earth cascade extraction, content of each component accumulates to different extent in the corresponding extraction tanks, and shows its characteristic color. When the production process conditions changed, the distribution of content of each component will be changed, and the...

description In the process of rare earth cascade extraction, content of each component accumulates to different extent in the corresponding extraction tanks, and shows its characteristic color. When the production process conditions changed, the distribution of content of each component will be changed, and the result is the movement of characteristic color. It integrates the image processing technology to identify characteristic color offset and fuzzy control. A rare earth extraction process control method composed of video monitoring and fuzzy controller is proposed. The technology is applied to a CePr/Nd extracting separation process. The results show the effectiveness of the control method.
