Influence of Sulfur Content in Tailings on Processes of Hypergene and Technogene Mineral Formation on the Example of Kavalerovo Tin-Ore District

Abstract:

The paper presents the results of the physicochemical modeling obtained with the use of the “Selektor” program of calculation of chemical equilibriums. We have determined the stability fields of hypergene and technogene minerals crystallized in the mining wastes (tailings) from the highly concentrated pore solutions forming the drainage waters of Kavalerovo district. Our investigations allowed us to obtained new data on the pH range of the hypergene and technogene mineral formation depending of the sulfur amount in the wastes coming with the flotation reagents and sulfides under conditions of the atmosphere influence and without it. This problem for the mining technogene system of the district under consideration is first proposed to be solved with the help of the method of the physicochemical modeling.
