Research of behaviour of the potassium peroxypentofluorotantalate monohydrate at heating

The interaction of vermiculite ores reject material with hydrochloric acid solutions using chemical and XRD analysis has been investigated. The opportunity of using the tails as raw material for magnesium and iron hydroxide, and also amorphous silica has been proved.

Geoecological validation of mechanisms and parameters of physical-chemical processes facilitating the in-depth processing of complex suphide ores and mining wastes

The advisability of processing copper-nickel ore dressing tailings of current production has been substantiated. The optimal parameters of metal leaching with sulphuric acid have been determined. In laboratory experiments the geotechnological extraction of non-ferrous metals from a leaching layer representing a tailing material of fraction +0.063 mm has been studied. When investigating the geotechnological processes of non-ferrous metal extraction on the basis of two copper-zinc ore deposits located in the Urals, the authors have come to the conclusion that heap leaching is of little use for the ores of the Letneye deposit. Leaching results for the Yaman-Kasy ore have shown more promise.

Artificial geochemical barriers as a way to solution of ecological and technological problems

Possibility of use as an artificial geochemical barrier of various mixtures chemically reactive minerals and rocks, products and wastes of chemical and metallurgical processing of ores and concentrates has been shown. Some examples of application of barriers for creation of anti-filtration screens with a view to purify waste and natural waters and to re-purify non-ferrous metals have been considered.
