METHOD OF SELECTIVE FLOTATION MANAGEMENT Russian patent published in 2017 - IPC B03D1/02 B03B13/00 

FIELD: chemistry.

SUBSTANCE: method of selective flotation process management comprises dosage of sulphidizer, activators, depressing reagents and collectors based on pulp electrochemical parameters. Potential difference between two electrodes: molybdenum and ion-selective electrodes, represented by argentite, or tin, or nickel electride, is measured in the pulp flow. Based on the deviation of bimetallic electrode pair potential difference from the predetermined optimum value, sulphidizer activator, xanthate and depressing reagents feeding is corrected to increase reagent dosage in case of increased potential difference, and to reduce reagent dosage in case of decreased potential difference.

EFFECT: increased feeding reliability and accuracy of depressing reagents dosage control.
