Clay is an abundant, naturally occurring, fine-grained material composed predominantly of hydrous aluminum silicates. Clay is not a single mineral, but a number of minerals. Clays fall into six general categories: kaolin, ball clays, fire clays, bentonite, common clays and Fuller's earth.
kaolin, ball clay, fire clay, bentonite, fuller's earth, and common clay and shale. Kaolin, or china clay, is defined as a white, claylike material composed mainly of kaolinite, which is a hydrated aluminum silicate (Al2O3·2SiO2·2H2O), and other kaolin-group minerals. Kaolin has a wide variety of industrial
The categories are kaolin, ball clay, fire clay, bentonite, fuller's earth, and common clay and shale. This section addresses emissions that result from the basic processing of clays that takes place between the mining of the raw material and the production of …

Kaolin, or China clay, is nearly white in color. It is distinguished from other industrial clays based on its fine particle size and pure coloring. Its ability to disperse in water make it an ideal pigment. The primary constituent in kaolin is the mineral kaolinite, a hydrous aluminum silicate formed by the decomposition of minerals such as ...
Six types of clays are mined in the United States: ball clay, bentonite, common clay, fire clay, fuller's earth, and kaolin. Mineral composition, plasticity, color, absorption qualities, firing characteristics, and clarification properties are a few of the characteristics used to distinguish between the different clay types.
Ceramics: Ball clays are used in many different industries, but in particular form a vital component in ceramic manufacturing. Kaolin ('china clay') produces a very white color when it is fired, but used alone it is brittle and weak and must be mixed with ball clay to produce a workable, malleable raw material.

Kaolin Clay vs. Bentonite Clay. What is the difference between kaolin clay and bentonite clay? One of the most important differences between these two clays, both of which are used to make facial masks and other beauty/skin treatments, is their pH levels. Bentonite has a higher pH than kaolin, which means it tends to be gentler and less irritating.

We have all types of minerals such as kaolin, ball clay, dolomite, limestone, silica sand, quartz and other minerals. Our principal activity was mining and processing all minerals-based products.
Ball clay, or 'plastic clay' as it is also known, is an extremely rare mineral, only found at a handful of locations around the world. It is a kaolinitic clay that commonly consists of 20–80% kaolinite, 10–25% mica, 6–65% quartz as well as organic matter.

BALL CLAY is a variety of Kaolinite, like china-clay. It differs from china-clay in having high plasticity and less refractoriness. In chemical composition, Ball clays usually contain three dominant minerals: from 20-80% kaolinite, 10-25% mica, and 6-65% quartz. In addition, there are other 'accessory' minerals and some carbonaceous material (derived from ancient plants) …

Ball Clay (OM4 in this case) always has less alumina and more silica than kaolin - so it takes more ball clay to get the same amount of alumina - then you have too much silica so you need to remove some. To get the same glaze use 14 OM#4 and reduce the silica to 25. Replacing kaolin with ball clay helps suspend glazes better and also will
Ball clay is extracted from the ground by surface working (open pit method), underground mining having ceased in 1999. Extraction involves excavators and dump trucks to selectively remove individual grades of clay to storage and blending facilities. The ratio of waste to clay is variable, but overall is in the order of 1 to 1.5. Ball clay ...
