China Clay is a clay mineral with the chemical composition AlSiO3O5(OH)3. It is layered silicate mineral. It is soft earthy, usually white in color, produced by the chemical weathering of Aluminium Silicate mineral like Feldspar. Commercial grades of China Clay are supplied and transported as dry powder form, semi dry noodle form or as slurry.
Applications:
- It is used in Cer/bamics for body & glazing of Tiles and Sanitary Wares.
- In paper it is used as filler. It is also used for paper coating purpose.
- It is used in paint also to extend Titanium Dioxide (TiO2) and modify gloss level.
- It is used in rubber to enhance reinforcement properties.

China clay belongs to the group of Minerals called Kaolinite. It is one of the most common minerals. Kaolinite clay occurs in abundance in soils that have formed from the chemical weathering of rocks in hot, moist climates—for example in tropical rainforest areas.
Comparing soils along a gradient towards progressively cooler or drier climates, the proportion of kaolinite decreases, while the proportion of other clay minerals.
BizWhite has been mining, processing, and supplying high quality Kaolin products, from its reserves in Gujarat.
On recognising the high demand for this multi-usage mineral and also the shortages of high-quality kaolin, we have positioned ourselves as one of the overriding kaolin china clay manufacturers and exporters from India.
Our Kaolin clay products are immensely used in the manufacturing of ceramics, papers, colours, vitrified tiles, soap, ultramarine, and various other purposes. Translucent quality, greater strength, and bright white appearance are the unique features of our Kaolin clay lumps.
We have our Kaolin Clay available in lumps, noodles and powder form.
China clay is characterized by its fine particle size, high brightness and rheology. We develop fine and ultra fine grades of Hydrous Kaolin from our best reserves, for various industries including Paint, Paper, Printing Inks, Paper board, Rubber etc. China clay is a natural mineral found in partly decompo-sed granite, an igneous feldsparic rock. Chemically, kaolin is a hydrated aluminium silicate containing Al2O3.2SiO2.2H2O. Kaolin was first discovered in the mountainous province of Kiangsi, China in A.D. 500. The word kaolin derives from the Chinese character kaolin which means high ridge. It was first used by the Chinese to make high quality porcelain.

We were the first to start a china clay processing plant in Bhuj-Kutch, Gujarat, by acquiring 100 hectares of land on lease from the government in 1983.
Back in 2018, a fully automated kaolin plant was established, featuring High Gradient Magnetic Separation (HGMS) and an automatic filter press that can handle up to 8000 tons every month.
In 2020, all plants were revamped to include a ball mill, centrifuge decanter, hydro cyclone, and filter press, which helped us achieve a capacity of 25000 tons per month.
A member of kaolinite family, Ball Clay is renowned for its plasticity and green strength. They consists varying proportions of kaolinite, mica and quartz, with small amounts of organic matter and other minerals, and are commercially values because they increase the workability and strength of various ceramic bodies and have white or near white firing characteristics. Ball clay is processed to minimize the levels of coarse particles. This enhances better workability and higher strength.
Applications :
It forms a major part of many ceramic applications, including sanitary ware, tiles, table wares and to an increasing extent non-ceramic applications like functional fillers and advanced application for example technical ceramics.
