Muscovite has a typical dioctahedral crystal structure. The atoms arranged in different directions of the crystal lattice will cause the anisotropy of the physical and chemical properties of the muscovite crystal planes, which also leads to the anisotropy of these crystal planes in flotation. In this study, Materials Studio 7.0 software was used to optimize muscovite crystal cells, and …
