Dec 03, 2014· The dolomite's decomposition occurs in a single stage which is a continuous and a slow process. At the temperature of 923 K, the complete decomposition takes 7 h and 25 min. The degree of dolomite conversion (α) was calculated based on the mass reduction measured at a given time and after the complete conversion, as illustrated in Fig. 4.
The invention relates to a method for obtaining treated dolomite for use as a remediation agent for the neutralisation and adsorption treatment of mining and metallurgical effluents and mine water, said method consisting of the following steps: reducing the dolomite particle size (with a purity percentage of between 80 and 99.9 %) by means of primary and secondary crushing; …
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 …
