Microwave heating makes changing the structure and technological properties of ores containing layered silicates possible. These changes take place at lower temperatures and times as compared with convective heating. This makes a framework for the reduction of energy input in thermal modification and for the inclusion of the technology in beneficiation process. This article discusses physical and chemical modification of layered silicates after microwave treatment. The authors describe how microwave heading modifies the structure ad process properties of ore containing layered silicates at lower temperatures than in convective heating.

The study was supported by the Russian Science Foundation, Project No. 19-79-10114.
