FIELD: ecology; processing industry; treatment of waste water, concentration of ores, processing of waste.
SUBSTANCE: proposed method includes delivery of air and discharge of foam product. Besides that, gas bubbles are additionally delivered for at least seven-fold increase of gas saturation of liquid being processed till forming of liquefied foam layer at duration and time interval of at least 1/7 of time required for processing the liquid in floatation plant; liquid foam is drained from floatation plant by gravity.
EFFECT: enhanced efficiency due to facilitated procedure of removal of foam sludge during floatation and electric floatation.
