On the example of waters from Komsomolsk tailings pond (Kemerovo region, Russia) with initial рН=6.5 and content of As and Sb amount to 0.25 mg/l and 0.85 mg/l, respectively, the possibility of using chemical reagents: lime milk, Na2S and FeSO4, for removal of metals and metalloids from the water right up to the maximum permissible concentrations (MPC) was shown. It was experimentally proved that all three used reagents are appropriate for arsenic immobilization. The following sequences of the reagents in increasing order of reagents efficiency for As removal can be constructed: lime milk<Na2S=FeSO4.
