Identity of the Composition of Colored Technical Gypsum Obtained as Waste of Vanadium Production
https://doi.org/10.18412/1816-0395-2023-5-28-33
Abstract
The results of identity composition of coloured technicl gypsum as a waste product of vanadium production at OAO "EVRAZ Vanadiy Tula" were presented. It was shown that gypsum is converted into anhydrite during heat treatment at 700 °C. It was proved that waste coloring is due to the presence of manganese hydroxide and vanadium oxide, their interaction during heat treatment forms manganese vanadate Mn2V2O7 and changes the color tone of the product. As decorative building materials, it is recommended to use colored gypsum-containing waste and products of their heat treatment.
