Studies of quartz sand samples from alluvial deposits of the Khanty-Mansiysk Autonomous Okrug were carried out. The construction of an enrichment plant using the technological principles of complex processing of primary loose masses is proposed. Tab. 2, ill. 1.
The use of feldspar rock (orthofira) and feldspar wastes of JSC "Molybdenum" (overburden pegmatites and "tails" obtained after ore processing) in the compositions of ceramic masses has been investigated. The dependence of sintering and phase formation on the type and amount of feldspar component and the amount of cullet in the charge has been established. A diagram has been developed for selecting the composition of ceramic masses with the required degree of sintering. The properties and phase composition of tiles with an optimal amount of feldspar components have been investigated. Tab. 4, ill. 2, bibliography: 3 titles.
