Limestone Wikipedia. Limestone is a carbonate sedimentary rock that is often composed of the skeletal fragments of marine organisms such as coral, foraminifera, and molluscs.Its major materials are the minerals calcite and aragonite, which are different crystal forms of calcium carbonate (CaCO 3).A closely related rock is dolomite, which contains a high percentage of the mineral dolomite, CaMg ...

The SO 2 absorbent (limestone) is offloaded at the factory, stored in a tank, and subsequently transferred to a wet ball mill and ground to increase the surface area, and consequently, the SO 2 absorption rate. Typically, limestone is ground to a particle size of 5–20 μm to ensure high desulfurization efficiency . The resulting mill slurry ...
