Magnetic Separator For Kaolin Clay What Is Kaolin Clay? Kaolin Clay is a combination of hydrated aluminosilicates composed of multiple minerals. The main mineral component is kaolin, and it also contains impurities such as quartz, smectite, illite and feldspar.
Dec 02, 2018 Magnetic separation in kaolin processing is a comparatively low cost and versatile technique. By variation of retention time, it is possible to achieve differing degrees of magnetic extraction at acceptable variations in costs. The HEMF process is not only low in operating cost, but also furnishes high yield 98-99% of kaolin product based on feed.
Mar 03, 2020 For ferromagnetic minerals such as magnetite and ilmenite or iron filings mixed in the process, it is more effective to use magnetic separation to separate kaolin. For weakly magnetic minerals, there are two main methods: one is to roast first to change the mineral to ferromagnetic iron oxide, and then perform magnetic separation; the other method is to use a high gradient strong magnetic field magnetic separation method Magnetic separation.
