Состав минеральной нагрузки и скорость ее достижения предложено характеризовать двумя безразмерными параметрами, которые зависят от интенсивностей субпроцессов. Параметр сорта частиц (B) однозначно определялся соотношением интенсивности отрыва к интенсивности захвата, а безразмерное время (D) – соотношением скоростей захвата и отрыва частиц к скорости подъема пузырька воздуха. Получено уравнение кинетики минерализации многими пузырьками в экспоненциальном виде, аналогичном уравнению первого порядка (Белоглазова). В константе скорости минерализации (Km) интенсивности субпроцессов захвата и отрыва определяют величину извлечения отдельным пузырьком (εbm) за время τm, а расход воздуха – суммарное извлечение ε.</p></abstract><trans-abstract xml:lang="en"><p>The joint review of particle capturing, aggregate separation and emerging subprocesses in the conditions of periodic froth free flotation showed that mineral load formed on a separate bubble during its ascent (τm). This load is part of the equilibrium mineral load that can be reached in an endless mineralization time. It was proposed to characterize the composition of mineral load and speed of its achievement with two dimensionless parameters, which depend on the intensities of the subprocesses. The type of the particle parameter (B) was uniquely determined by the ratio of separation intensity and capture intensity, and the dimensionless time D – by correlation of particle capture and separation speeds to the air bubble rise velocity. The kinetics equation of mineralization with many bubbles was formulated in the exponential form similar to the first order equation (Beloglazov’s equation). In the mineralization rate constant (Km), capture and separation subprocess intensities determine the value of individual bubble extraction (εbm) in time τm, and the air consumption defines the total removal value ε. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>флотация</kwd><kwd>пузырек</kwd><kwd>кинетика</kwd><kwd>минерализация</kwd><kwd>субпроцесс</kwd><kwd>интенсивность</kwd></kwd-group><kwd-group xml:lang="en"><kwd>flotation</kwd><kwd>bubble</kwd><kwd>kinetics</kwd><kwd>mineralization</kwd><kwd>subprocess</kwd><kwd>intensity</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Zheng X., Johnson N.W., Franzidis J.P.
