FIELD: chemistry.
SUBSTANCE: group of inventions relates to control float chambers for separation of substances in the feed material in line of foam flotation for separation of substances, for example minerals containing valuable material from loaded material in form of ore containing empty rock. Method includes a step of executing a control program to maximize foam stability during operation of chamber. Control program includes a step of varying gas flow into in chamber in a specified sequence of steps. Method also includes a step of estimating foam stability at every gas flow rate. There is a step of continuing stepped change of gas flow rate until foam stability reaches peak stability of foam or stays in a predefined range of peak foam stability of chamber.
EFFECT: technical result is high efficiency of controlling float chambers.
