Mica Beneficiation process
Mica is the most widely distributed rock-forming minerals, and The most common mineral species are biotite, muscovite, phlogopite, lithium mica, sericite. According to the nature and the different types of mica material, there are different methods. Sheet mica according to the shape. Crushed mica adopts winnowing.

Mica beneficiation machine
n mica beneficiation plant, the most used equipments are crusher machine and grinding mill.
Mica crusher
Jaw crusher is the most commonly used crusher machine for crushing mica. The capacity of small jaw crusher is 1t/p. While the large scale jaw crusher is 300-800 tons/p.
Hammer crusher is another widely used mica crushing machine. It can crush mica into mica flake less than 15 mm.
Of course there are other crushers to be chosen to crush mica. The crushed mica is the raw materials for mica paper and mica powder.
Mica grinding mill for mica powder
Ball mill is the most common mica mill machine. The finished size is 0.074-0.4mm, and the capacity of ball mill is 1-30 ton/p.
Raymond mill is also the common mica mill used in mica beneficiation plant. It's fineness can be upto 0.044mm. The capacity is 1-3t/p.
The common mica powders are 6-10 mesh, 10-20 mesh, 20-40mesh, 40-60 mesh, 80mesh, 100mesh, 200mesh, 325mesh, 400mesh, 600mesh, 800mesh, 1000mesh, 1250mesh, 2500mesh.
Besides these mica crushing and powder machine, there are other important beneficiation processing machinery.
Vibraitng screen is the essential mica screening machine. According to the requirements of fineness, we can install the different layers with different screen pore size.
