The difference between bauxite, kaolin and clay
Aluminum ore is actually refers to the industry can use, in order to gibbsite, boehmite and diaspore as the main mineral composition of the ore collectively. Application of bauxite has two aspects of metal and non-metal is the best raw material for the production of metal aluminum, and it is also the main application areas.
The clay is clay sand. Rarely, sticky soil, water is not easily through clay plasticity including kaolinite, halloysite, very small particles (<2 m). In addition to aluminum silicate clay also contains small amounts of magnesium, iron, sodium, potassium and calcium. In the model industrial, manufacturing and art model.
The quality standard of kaolin is mainly composed of small, flaky, tubular and laminated kaolinite minerals less than 2 microns. Kaolinite minerals: cluster by kaolinite, dickite, nacrite, halloysite etc., chemical formula and ideal for AL2O3-2SiO2-2H2O, the main mineral is kaolinite kaolinite and kaolinite mineral water, in addition to the cluster, and montmorillonite, illite, quartz and feldspar, Ye Lashi and other associated minerals. Kaolin plasticity, adhesion, certain drying strength, sintering and sintering whiteness and other special properties, make it become the main raw materials Kaolin ceramic ceramic production, is a mainly composed of kaolin clay. The name was first found in kaolin village, northeast of Jiangxi, Jingdezhen province.
