METHOD OF CONTROLLING FLOTATION PROCESS Russian patent published in 2016 - IPC B03D1/00 B03B13/00 B03D103/00 

FIELD: mining.

SUBSTANCE: invention relates to field of minerals and may be used for control of flotation to increase its efficiency. Method of production of flotation process involves controlling density of initial supply, air flow in chamber and pulp level in flotation machine. Additionally ore consumption is measured, intensity of noise and active power of mill motor, flow rate and density, pulp aeration in air flow rate, water consumption into floatation chutes, reagent consumption, levels of commercial product in flotation machine and technological sumps, opening degree of process valves, volume of industrial recleaning, pH and temperature of pulp. Obtained data is processed and degree of effect of each parameter, such as ore consumption, noise intensity and active power of mill motor, flow rate and density, pulp aeration in air flow rate, water consumption into floatation chutes, reagent consumption, levels of commercial product in flotation machine and technological sumps, opening degree of process valves, volume of industrial recleaning, pH and temperature of pulp into technological process in flotation machine. Then from all measured parameters affecting technological process, parameters are selected with coefficient of linear pair correlation is more than 0.18 and determined by regression analysis relationship between which influence parameters and technological process in flotation machine. Value of content of useful component in product of flotation is calculated by mathematical relation: Y=A₀+A₁X₁+A₂X₂+…A_nX_n, where A₀ is free member; A₁, A_2…A_n are equation coefficients; X₁, X₂…X_n are impacting process parameters, obtained magnitude is analysed and, if mismatching to specified process parameters, corrected control effects on control technological parameters so that deviation between preset and actual value of content of useful component is not more than 0.2 % relative.

EFFECT: higher quality control of foam flotation enrichment by taking into account all influencing controlled parameters of process and quality control of output product so that deviation from preset quality is minimum.
