Abstract: Mineral resources are the foundation of social and economic development. According to the goal of realizing high−quality development of mineral resources in the new period of China, it is necessary to build green and highly efficient mines by using information and digital technology. Intelligent beneficiation is a part of intelligent mine, and its implementation is based on the informatization and digitalization of mineral processing. Taking foam flotation as an example, the common methods of foam state informatization were combed, and the digital applications of foam state information were further described, then the development and promotion direction of intelligent flotation process was discussed. The aim is to facilitate the advancement of the research process related to advanced technologies in the field of intelligent mineral processing.
