In order to improve the stability of flotation slurry liquid level and the quality of flotation
products，reduce the equipment failure rate and equipment maintenance cost，and save labor cost in the con⁃
centrator of Yunnan Hualian Zinc & Indium Stock Co.，Ltd.，the automatic control transformation of flota⁃
tion machine liquid level was carried out. The transformation and application show that compared with the
traditional manual liquid level control of flotation machine，the liquid level automatic control system of flota⁃
tion machine can be constructed by adding liquid level measuring device，liquid level controller and pneu⁃
matic actuator. The parameters of flotation liquid level system can be set up in DCS remote operation station
to monitor the production status of flotation machine and realize the rapid and stable adjustment of flotation
machine liquid level.
