Oct 19, 2015 Thermal decomposition of dolomite in the presence of CO 2 in a calcination environment is investigated by means of in situ X-ray diffraction (XRD) and thermogravimetric analysis (TGA). The in situ XRD results suggest that dolomite decomposes directly at a temperature around 700 C into MgO and CaO. Immediate carbonation of nascent CaO crystals leads to the formation of calcite as an ...
Following the crushing process, intermediate stone stockpiling guarantees a steady supply of stone to the downstream processes. Quarries operate by day during the week, while transformation installations generally work around the clock. In our lime and dolime-producing plants, stone fractions bigger than 20 mm are usually sent to calcining kilns.
