Clay ores are the main minerals that make up claystones and soils, they are a number of aluminium- and magnesium-containing dominant hydrous silicate minerals, including mainly minerals of the kaolinite, illite, montmorillonite, vermiculite, and seafoam groups. The particles are very fine, generally less than 0.01 mm. It has different degrees of plasticity when water is added. Clay mineral crystal structure and crystal chemical characteristics determine that it has the ion exchange, and clay minerals and the role of water produced by the expansion, dispersion and cohesion, viscosity, thixotropy and plasticity and other characteristics of the industry has been widely used, in addition, some of the clay minerals and the reaction of organic matter to form an organic complex, improve its performance, expand the scope of application, but also as the analysis of identification of minerals based on.

Clay minerals investment prospects

1、Kaolin is mainly used as ceramic raw materials, fillers and coatings for paper making;

2, mainly composed of montmorillonite bentonite is used as drilling mud, catalyst and bleaching agent for refining oil, binder for iron ore pellets and cast sand binder;

3, Aubergine clay and seafoam clay is the manufacture of salt-resistant mud quality raw materials, oil and grease decolourant and absorbent;

4、In animal nutrition research, it can be used as feed additives to replace antibiotics, which can promote the growth of animals and achieve better feeding results.

Clay mineral processing applications

Due to the technical processing of such mineral raw materials and product requirements, and the main use of different so processing methods or beneficiation technology varies. For example, the processing of kaolin raw materials, generally include: crushing - grinding - flotation (magnetic separation) - classification - bleaching - concentration - filtration - drying. Crushing generally use jaw crusher with cone crusher and other equipment for the crushing of raw minerals, grinding generally use ball mill for grinding processing, flotation used to remove anatase, magnetic separation used to remove iron oxide; bleaching with chlorine, sulphur dioxide or zinc thiocyanate as bleaching agent, the purpose is to dissolve rust and other coloured substances, increase product whiteness. Drying is to use the dryer to dry and dehydrate the minerals. The whole process users can choose according to their own processing requirements and production of finished products.
