Influence of the presence of carbon dioxide on chemical composition of water in contact with mining waste

Abstract

Nowadays post mining areas are often reclaimed and used housing areas, sports areas and recreational areas. Mining waste weathering is a significant factor influencing the condition of the surrounding water and soil environment. It is necessary then to evaluate susceptibility of the waste to weathering in given conditions and predict the rate of the processes. The paper presents initial results of an experimental study evaluating the influence of the presence of CO2 on the composition of leachate obtained when mining waste is exposed to water. The results of the experiments confirm the importance of the oxidation of pyrite and dissolution of carbonate minerals in changing the pH of water interacting with the waste.
