FIELD: hydraulic metallurgy. SUBSTANCE: absorption barrier is placed on the way of industrial waste liquids streams migration beyond the limits of impurities source. Barrier is a chain of spaced for 4-5 meters wells, which are pumped with gel-forming solutions in that has forming gel duration of 1 1,5 hours and forms gel, for example, alumosilicate oxalate, that absorbs heavy metals. EFFECT: increased heavy metals extraction from industrial waste liquids efficiency. 2 tbl
