Tailing dumps at the Krasnorechenskaya concentration mill (Primorskii krai, Russia): Geochemistry and mineralogy

Resumo

This study presents the mineralogical and geochemical characteristics of tailing dumps at the Krasnorechenskaya concentration mill (Primorskii krai, Russia). Primary ore minerals and newly forming mineral assemblages were also investigated. According to the obtained data, the possible reserves of the major elements accumulated in these tailings were estimated. It was shown that the tailing dumps at the Krasnorechenskaya concentration mill are potentially promising for secondary recovery. The tailing sediment has natural geochemical stratification and the specific correlations of elements are typical for each selected layer.
