The mica beneficiation process varies according to the origin and the nature of the ore. The dry process and the wet process are as follows:

Dry beneficiation process: raw ore → coarse crushing → decontamination → fine crushing → sorting → product superfine crushing → classification → packaging

Wet dressing process: raw ore → washing → coarse crushing → fine crushing → grinding → sorting → product dehydration → drying → classification → packaging

The process of Guangdong Xinhui Huanyu Mica Wet Processing Factory is: flaky mica → wheel milling → slurry purification → storage → product dehydration → drying → grading → bagging.

A crushed mica mine in Jiangxi can obtain a concentrate with a muscovite content of 99% through crushing→grinding→de-sludge (-10μm)→flotation (one coarse and two fine)→superfine grinding process. The final recovery rate is 81. %.

The purification process of a sericite mine in Hunan is crushing→grinding→flotation (one coarse and two sweeping five selection process)→filtration→drying→bagging.

The crushing and grinding equipment is commonly used in various jaw crushers , claw crushers , ball mills , rod mills, wheel mills, pulverizers , etc.; grading equipment commonly used vibrating screens, plane rotary screens, cylinder screens, high square screens , spiral classifier, cyclone, etc.; sorting equipment commonly used vibration air sorting machine, chamber air sorting machine, shape air sorting machine, flotation machine, hydrocyclone and special for shape and friction sorting Equipment, etc.
