Мaterial composition and thermal properties of chrysotile asbestos enrichment tailings of the Kiembaevsky deposit
Year: 2024
Type: article
Abstract: Technogenic formations of JSC Kiembaevsky GOK «Orenburg Minerals» obtained during the extraction and enrichment of chrysotile asbestos can serve as a potential raw material for the production of propants. It was found that the loss of mass of the material during firing is on average 13‒14 % and is associated with the dehydration of basic minerals. The transition of serpentine group minerals to forsterite begins at 818,4 °C and ends at 846,4 °C. At temperatures above 850 °C, all serpentine will turn into forsterite and enstatite. The content of forsterite in the fired material varies from 80 to 90 wt. %. Ill. 4. Ref. 25. Tab. 1.
