Digital technologies for optimizing the dosing of flotation reagents during flotation of non-ferrous metal ores

Currently, progress in the field of flotation enrichment is closely related to the development of measuring technology, which ensures the formation of the most complete information space for the object under study, and the use of the latest mathematical and statistical methods for analyzing the data obtained, which are the basis of digital technologies. The article analyzes the modern methodological approach to solving the problem of optimization of reagent flotation modes in the study of mineral enrichment. This study is based on the study of electrochemical processes occurring directly in the flotation pulp. In the course of laboratory studies, the multifunctional effect of sodium sulfide in the flotation of non-ferrous metal ores was studied. A neural network model has been developed and tested to optimize the indicators. It is established that by optimizing the supply of sodium sulfide and stabilizing the potential of Ag2S, it is possible to increase the technological indicators of enrichment.
