Cleanup of mine waters of the mining industry from heavy metals ions by bentonite clay
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.
