| Abstract: | Glass-ceramics have been produced via vitrification from manganese crust tailings with over 23% reduction in tailings volume.
The crystalline behaviour of parent glass and glass-ceramics were investigated using DTA, TGA, XRD, and SEM/EDS. XRD analysis
revealed that the major crystalline phase was iron manganese oxide. The Vickers microhardness (H
v) was 9.74 MPa, the indentation strength (K
c) was 1.88 Mpa m1/2, and elastic modulus (E) was 140 MPa. The properties of the glass-ceramic compared well with known research and industrial glass-ceramic materials.
Results suggest that manganese crust tailings have potential to be vitrified into useful, marketable glass-ceramic materials. |
