Hydrochemical Anomalies in the Vicinity of the Abandoned Molybdenum Ores Processing Tailings in a Permafrost Region (Shahtama, Transbaikal Region)

The mobility of chemical elements during the transition from molybdenum ore processing waste to aqueous solutions and hydrochemical anomalies a number in surface underground waters vicinity an abandoned tailings dump were investigated. It is shown that alkaline earth metals have high mobility—the main rock-forming components (sodium, lithium, magnesium, strontium), which are released into solution due leaching minerals host rocks, as well with zinc, cadmium, manganese, nickel, dissolution sulfides. Elements include Sb, Co, Cu, Be, Se, Tl. Medium has As, element first hazard class, Mo, Fe, Pb. Hydrochemical arsenic, molybdenum, lead been determined. nature arsenic most likely related regional background, while source cadmium studied. forms presence ponds on free-ion sulfate complexes. For example, samples Shakhtama River groundwater, we found carbonate, bicarbonate, hydroxide information obtained should be taken account when planning measures for purification groundwater metals. Additional studies consider using drinking water supply.
