Methods of using overburden and a treatment by-product of feldspar mining in production

This study determines the possibility of using a by-product from the treatment of feldspar ores and overburden from their mining in some areas of production at JSC Vishnevogorsk. In particular, it considers methods for using the by-product as an additive for the production of building ceramics, a raw material for the production of alumina and soda-potash, and material for the reclamation of disturbed lands. The products of crushing coarse overburden rocks were examined for compliance with the regulatory requirements for the production of heavy concrete to determine the possibility of their use as coarse aggregates. During the research, standardized and special methods were used to study the physical-chemical and physical-mechanical characteristics of such materials. The results of this study may be useful for increasing the economic efficiency of mining enterprises and improving the environmental situation in the region.
