Abstract

The paper presents characteristics of chemical and microelement composition of drainage water in dumps and the septic tank of the tailing dump in three gold ore deposits of Eastern Transbaikalia localized in a single ore field in the rocks of base composition. The ionic composition of all samples contains sulfate, and two of the samples contain nitrate-sulfate water due to explosives used during ore extraction and cyanide technology employed in gold extraction. Low concentrations of bicarbonate in water of the dumps at pH 7.27-7.36 allowed conclusion that the acidic potential should be neutralized by non-carbonate minerals of the host minerals, which requires special studies. The pH value plays a dominant role in distribution of microelements in water, however, the impact of geochemical features of ores and host rocks is also revealed, though for some elements this dependence is not found.
