On October 28, 2021, RIVS received a patent for the invention “Method for automatic control of technological grades of ore in a stream”.
Patent for invention No. 2758305, issued by the Federal Service for Intellectual Property of the Russian Federation, is valid until March 30, 2041. The authors of the invention: Zimina Anna, Trushin Aleksey, Bondarenko Alexander, Katsman Yakov.
The proposed invention relates to methods for controlling technological grades of ore in a stream and can be used in the field of mineral processing, metallurgical and other industries. This method consists in setting the final technological indicators of the efficiency of the flotation process, carrying out a representative sampling of the flotation feed pulp.
- one part of the sample is analyzed for the content of chemical elements in the solid phase of the pulp,
- the other is subjected to dehydration, drying and analysis of the color characteristics of the resulting dry surface, control of the regime parameters of the grinding and flotation cycles and the corresponding technological indicators of the efficiency of the flotation process,
- further, an archive of initial data is formed containing information on the numerical values of the color characteristics and the elemental composition of the flotation feed, the values of the controlled technological parameters and the efficiency indicators of the flotation process at each measurement cycle.
