Geochemical and mineralogical assessment of sedimentary limestone mine waste and potential for mineral carbonation.

This paper attempts to evaluate the mineralogical and chemical composition of sedimentary limestone mine waste alongside its mineral carbonation potential. The limestone mine wastes were recovered as the waste materials after mining and crushing processes and were analyzed for mineral, major and trace metal elements. The major mineral composition discovered was calcite (CaCO) and dolomite [CaMg(CO)], alongside other minerals such as bustamite [(Ca,Mn)SiO] and akermanite (CaMgSiO).
