A sorption method is proposed for cleaning industrial effluent with a new nanostructured complex sorbent based on Taganskoe deposit bentonite clay and mineral wool production waste. It is shown that with mechanical activation of bentonite clay together with mineral wool production waste there is an increase in clay particle content with a size less than 1 μm. It is established that for comprehensive and effective cleaning of electrolysis effluent from heavy metal ions a nanostructured complex sorbent (NSCS) is recommended based on bentonite clay from the 11th level and mineral wool production waste with observation of the following optimum conditions: 2:1 ratio of components in NSCS of 11th level bentonite clay : mineral wool production waste; rational mechanical activation scheme with grinding and nanostructuring of complex sorbent starting materials for 15 min; S:L = 1:100 (1 g of paste (in terms of dry substance) to 100 cm3 clean water); sorption time 3 h with constant stirring.
