What is the beneficiation and purification method of mica

The method of beneficiation and purification of mica varies depending on the nature and type of mica. The flake mica generally adopts hand selection, friction selection, shape beneficiation, etc.; broken mica adopts air separation and flotation. According to the structural characteristics of the mica itself and the mineral composition of the ore, the mica is selectively crushed. While the mica is peeled into thin slices, the harmful impurities such as quartz, feldspar, a small amount of clay minerals and vermiculite in the ore are finely ground, and then sieved and winded. This method is currently the most economical and effective method for mica beneficiation, and it is also one of the beneficiation methods that have been verified by many manufacturers for many years.
