In a hydrocyclone, a slurry enters through a tangential inlet, giving rise to a vortex in the stationary body. The particles and fluid are accelerated centrifugally and separation occurs in the radial direction. Denser materials migrate to the outer wall of the hydrocyclone chamber, while less dense materials move toward the inner axis. ...

The highest decomposition rate of calcite is above 760 °C based on the CO 2 gas analysis and the decomposition seems to be completed above 850 °C, Fig. 11, as we also see in the XRD analysis where calcite and calcium oxide co-exist at the sample treated at 760 °C. This indicated that the decomposition needs higher temperature to be completed.
