Attenuation of antimony in groundwater from the

Mining activities such as the creation of adits have changed the redox conditions of groundwater at the XKS Sb mine. After mining, sulfides in the host rock and mineralized zones such as stibnite, pyrite, and arsenopyrite are oxidized due to various redox conditions (Li et al., 2013). This results in elevated Sb, As, Fe, and Mn …

Dolostone (Limestone)

Dolostone (Limestone) The principal mineral of limestone is calcite (CaCO3), a form of calcium carbonate. Dolostone is quite similar to limestone, but is composed mostly of the mineral dolomite (CaMg (CO3)2). Both are sedimentary rocks that occur as thin to massive beds of fine- to coarse-grained rock. Their color is typically some shade of ...
