The temperature required for the decomposition of dolomite and dolomitic limestone is usually in the range of 500 deg C to 750 deg C. The smaller size limestone is more suitable for calcination in rotary kilns and it allows optimum residence time. The lower calcining temperature also allows less fuel consumption.The calcite in the limestone changes and fossils and layering in the original limestone disappear as interlocking grains grow. If the limestone is pure, a white marble is formed. Limestones may include layers of clay or sand which may form the attractive flow banding and colours found in decorative marble.Calcite is the major component of limestone (typically more than 95%), and under surface conditions, limestone will dissolve to varying degrees (depending on which minerals it contains, other than calcite), as shown in Figure 5.12. Limestone also dissolves at relatively shallow depths underground, forming limestone caves.Calcite ( calcium carbonate) Chalk is a soft, white, porous, sedimentary carbonate rock.
