Abstract

The sorption of bentonite clay of Tagansky deposits of the East Kazakhstan region of the heavy metals ions (Си2+, Pb2+, Cd2+, Zn2+) of mine water Belousov polymetallic Deposit was studiet. It is established  that the use of bentonite clay, pre-treated by10% sulphuric acid for und 4 hours at 1200С for the purification of mine water from ions of heavy metals at selected optimal conditions: pH 8,0-8,5, mixing time of 15 minutes, consumption of adsorbent 6 g/dm3 allows to reduce the pollution of mine water from ions. The degree of extraction of metal ions Сu2+, Pb2+, Cd2+, Zn2+ is 99,6%, 94,7% per cent, 98,9% and 99,5%, respectively.
