METHOD OF LOCALIZATION OF TECHNOGENIC COPPER Russian patent published in 2002 - IPC

FIELD: ecology. SUBSTANCE: invention relates to environment control and designated for prevention of soils, surface and subsoil waters from pollution with technogenic copper. Invention proposes to use dolomite or dolomitized limestone as a precipitant in geochemical barrier. Copper is precipitated as deviline that is a binary basic copper and calcium sulfate. Stability of binary salts to dissolving ensures to use dolomite completely in practice that enhances the capacity of barrier and provides safety retention of copper under conditions of high parent concentrations. Two latter features of the method proposed ensure to make barrier not only above the pollution source but inside its directly also that results to decrease of technogenic pressure on environment. EFFECT: improved method of localization, enhanced resistance of barrier and its capacity by copper. 2 cl
