Sericite, belongs to subspecies of muscovite, is one kind of natural fine grained mica and phyllosilicate. It is monoclinic crystal and scaly shaped with silk luster. After completely cleavage, it can be split into thin sheet with big diameter-thickness ratio.
China possesses rich sericite ore resources. They are widely distributed around the nation, but only a small part of them deserve to be exploited. According to different causes of ore deposit, sericite ore can be divided into Schist type (Chuzhou city, Anhui province), Porphyry alteration type (Jingdezhen city, Jiangxi province), Volcanic rock alteration type (Nanan city, Fujian province), etc. Among all types of sericite ore, schist type sericite ore in Chuzhou city, Anhui province has highest developing and utilizing value, because it possesses the most obvious mica mineral features.
Henghao is located in Chuzhou city which is known as “Hometown of Sericite”. In these two decades, Henghao technology team focus on pursuing in-depth researches on Chuzhou sericite ore, designing a complete set of wet beneficiation techniques specifically for schist type ore, and solving technology problem of fine quartz separation and perfect sericite sheet protection which has filled the technical blank of schist type sericite ore dressing process.
Through advanced wet splitting technology, accurate classification process, and unique method to wipe out the heavy metal to reprocess sericite. Based on above process, the produced sericite powder are exquisite with silky smooth and with high purity, and are widely used in pressed powder, eye shadow, lipstick, BB cream, liquid foundation, loose powder, talcum powder, eyeliner, sunscreen cream, skin care cream, skin lotion, facial mask, etc.
Anhui Heng Hao Science and Technology Co., Ltd. is adhering to advanced technology research and development to produce cosmetics-used mica powder, sericite powder, phlogopite powder, silicon processing powder, and activated bentonite.
In the past two decades, Heng Hao has consistently focused on the unique wet grinding, purification, grading, activation and cladding to produce crystal clear and silky soft natural mica powder and sericite powder.
