The monograph presents the results of an experimental study of the galvanic coagulation phase formation process in the system of short-circuited galvanic contacts iron - carbon (coke) that was carried out on the current model of industrial galvanocoagulator, water permeability and model solutions of inorganic salts hydroxide structures in situ. The influence of the galvanocoagulation parameters on the phase composition and mass of the formed precipitate, the value of the hydrogen index and the chemical composition of the dispersion medium are established. The conditions of the galvanic contact system transition to the steady state are discovered and the influence of the operating time of the iron component on the chemical and phase composition of the formed pulp is determined. Physicochemical and colloid-chemical mechanisms of phase formation in the system of short-circuited galvanic pair steel-3 - coke are revealed. The separation possibility of dispersed products of galvanic coagulation process by adaptation of traditional methods of natural raw materials separation is shown. Examples of electrolysis, galvanocoagulation and cementation in technological schemes of liquid waste disposal of galvanic productions are given it the monograph.
