Abstract
The research involves the calcination of SiChuan ShiMian asbestos tailings with ammonium sulfate in order to extract magnesium. This chapter studies the effect of different calcination conditions on the magnesium extraction rate and the mechanism of calcination of asbestos tailings mixed with ammonium sulfate. The results are characterized by XRD, TGA, and elemental analysis. The results show that as the temperature rises the magnesium extraction rate first increases and then decreases. Optimal experimental conditions are 600 °C of calcination temperature and 1 h of calcination time, by means of which a magnesium extraction rate of 68.56 % can be achieved.
