Исследован электрофлотационный процесс извлечения дисперсной фазы кобальта из сточных вод предприятий цветной металлургии. Показано, что в диапазоне плотности тока 0,3–0,5 А/л степень очистки сточной воды от дисперсной фазы соединений кобальта составляет 97–99 % при времени обработки 8–10 минут. Проведение процесса электрофлотации с предварительной флокуляционной обработкой воды позволяет сократить время до 3–5 минут и затраты электроэнергии в 2–3 раза.A process of the electroflotation of recovery of a dispersed phase сonnections of a cobalt from waste waters of firms of non-ferrous metallurgy has been studied. It is shown that in the range of current densities 0,3–0,5 А/l the degree treatment of the waste water from dispersed phase of metals is 97–99 % and time treatment of waste water 8–10 min. The process of electroflotation combined with flocculation treatment of the waste water enables time to 3–5 min and electric power consumption by 2 to 3 times.
