Kaolin is a mixture of various minerals. Its main component is kaolinite; it often contains quartz, mica, feldspar, illite, and montmorillonite. It is formed by rock weathering. Kaolin is widely used in ceramics, medicine, coated paper, cosmetics, as food additive in toothpaste, as a light diffusing material in white light bulbs. Kaolin is also an important component in porcelain. It is also used in paint to extend titanium dioxide and modify gloss levels; in rubber for semi-reinforcing properties. Kaolin was long used in the production of common smoking pipes in Europe and Asia. Due to its various application, kaolin is an crucial mineral in economy development. Kaolin beneficiation has good market prospect.
Kaolin beneficiation process
Nowadays, global economy is highly developed, the increasing volume of various mineral resources are required for many applications. As we all know, raw and Low grade kaolin doesn’t fit for final applications. It needs to be processed through beneficiation process. Several stages involves in kaolin beneficiation process, including crushing; grinding; sometime screening; gravity separation; magnetic separation and flotation etc. Crushing and grinding stages are aim to reduce the raw kaolin to fine particle size. Screening is the auxiliary process between the former two stages; it is for screen the required materials. Sometimes flotation-magnetic-gravity separation methods maybe used for refined kaolin concentrate for certain applications.
Kaolin beneficiation equipment
Kaolin beneficiation is to process the raw materials into specific products to achieve its economic value. In the beneficiation process, jaw crusher is known for primary crushing due to its big crushing ratio. Impact crusher and HCS cone crusher are excellent for secondary crushing. Ball mill, high pressure mill and ultrafine mill are for fine grinding after crushing process. There are also auxiliary equipment such as vibrating screen, feeder and belt conveyor.
