What are the minerals contained in mica plates?

The insulating epoxy plates in the tailings are mostly mica plate vein minerals, and the selected element terbium minerals are mainly terbium mica, a small amount of white mica, phosphorite and tenebrionite. Other vein minerals are mainly sodium feldspar, followed by quartz, potassium feldspar, topaz, sericite and kaolinite.

What are the minerals contained in mica plates?

The metallic minerals in mica plate ore are more complex, and the epoxy plate contains a wide variety of minerals, both primary minerals and secondary oxidized minerals; oxidized minerals, hydroxides and sulfide minerals. However, the content of various minerals is very small, and only denier minerals can be recycled as by-products. Other metallic minerals are magnetite, hematite, dannite, fine crystal, cassiterite, alteration dislocation, soft manganese ore, phosphorite, pyrite, chalcopyrite, sphalerite, galena, pyroxene, spotted copper ore, and secondary oxide minerals are limonite epoxy platelet, copper blue, etc.

As the minerals are taken from Dan Clay re-election tailings, mica plate has been crushed and ground before re-election, many mineral embedding phenomenon has been destroyed, it is difficult to observe the complete embedding characteristics to find the remaining part in the particle fraction, the sand mineral characteristics observed under the microscope through the ground sand grinding flakes are detailed as follows: clanging mica, scaly, foliated, flaky, thick plate, rarely in strips, usually irregularly foliated, separated developed, often in flakes. It is mainly associated with sodium feldspar, followed by quartz, potassium feldspar, topaz, kaolinite and sericite. Nucleated mica coexists with sodium feldspar in various forms, some are separated and accounted for by nucleated mica and wrapped by nucleated mica; some are accounted for by quartz grains, sericite or kaolinite. Sodium feldspar and sericite are constantly growing, generally sodium feldspar is mostly distributed at the edge of sericite, some sodium feldspar is accounted with kaolinite and sericite, forming two or three epoxy flake minerals together with sericite. Other vein minerals, potassium feldspar and quartz, are also mostly epoxy sheets on the surface of mica, and a very small amount of mica is wrapped with paraminerals such as danite and altered parasites. Very small amounts of pit mica are filled with dense black minerals, or limonite, magnetite, etc., mostly distributed in the dissociated layers of pit mica.
