| Abstract: | The potential of the tailings from the Morille scheelite-bearing calc-silicate deposit as a commercial raw material for inert glass-ceramic was determined. Nucleation and crystal growth temperatures of glass were studied. The temperatures of maximum nucleation rate of the parent glass are 612 °C and 660 °C and crystal growth is at 776 °C and 1047 °C. At 776 °C a glass-ceramic of nepheline, wollastonite and akermanite is formed. In glasses treated at higher temperature nepheline becomes unstable and at 1047 °C a wollastonite-akermanite glass ceramic was obtained. The leaching tests show that the potentially toxic elements are effectively bound in the structure of the glass-ceramic, which can be considered inert. |
