Predicting water contamination during the development of chromite deposits

Physicochemical numerical simulation of the system water-serpentinized ultramafic rocks of the Aganozerskoe deposit (systems closed and open with respect to atmospheric oxygen and carbon dioxide) indicates that wetting and oxygen access to chromite ore and mined processed rock in the open system should result in chromite oxidation and enhance Cr migration. In the closed system, in which the processed rock is stored at the bottom of a water body and is inaccessible to atmospheric gases, the oxidation dissolution of chromite is less intense.
