The U.S. Bureau of Mines is developing techniques to optimize the design of mineral processing equipment and to control the mineral processing sequence. Emphasis at the present time is on the optimization of froth flotation. The optimization of flotation devices, such as the air-injected hydrocyclone, has been accomplished using genetic algorithms. An expert system for the flotation of phosphate has been developed. Control of various operations in flotation is being studied using a combination of fuzzy logic and genetic algorithms. Combining the control capabilities of fuzzy logic with the search capabilities of genetic algorithms makes the production of an expert system that develops rules on-line a distinct possibility. Also, the use of computer vision for on-line analysis of processing streams in phosphate flotation is being investigated. This paper describes the progress to date on these processing problems.
