We are offering silica sand. Silicon and oxygen are the earth's two most abundant elements and together they make silica, one of the earth's three most common rock forming minerals the first industrial uses of crystalline silica were probably related to metallurgical and glass making activities a few thousand years bc. It has continued to support human development throughout history, being a key raw material in the industrial revolution especially in the glass, foundry and ceramics industries. Silica contributes to today's information technology revolution being used in the plastics of computer mouses and providing the raw material for silicon chips.

We are offering ball clay. Ball clay is a fine grained and plastic sedimentary clay, mined and processed (water washed and filter pressed). The inherent ball clay is valued in its high plasticity, dry strength, green strength, bonding nature etc. The high plasticity facilitates shaping and finishing of ceramic bodies and high strength allows un-dried clay article to keep their shape and withstand all types of molding, shaping and conveying during manufacture. Hence asha-07 ball clay is recommended for refractory products, ceramic granite tiles, glazed tiles, table ware & high tension electric insulators etc. A vital material in 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. as a result of their sedimentary origin, raw ball clays have a wide range of colors. however, many of them are valued by the ceramics industry for their white-firing properties, which are determined by the levels of iron and other coloringfluxing oxides within the clay.

Tableware: ceramic tableware utilizes ball clay to provide high plasticity and a good white-fired color, combined with kaolin, feldspar and quartz. Glazes and engobes: ball clays are also used in the production of coatings for ceramic products to ensure the perfect finish.

We are offering bauxite ore. Bauxite is a naturally occurring, heterogeneous material composed primarily of one or more aluminum hydroxide minerals, plus various mixtures of silica, iron oxide, titania, aluminosilicate, and other impurities in minor or trace amounts. The principal aluminum hydroxide minerals found in varying proportions with bauxites are gibbsite and the polymorphs boehmite and diaspore. bauxites are typically classified according to their intended commercial application: abrasive, cement, chemical, metallurgical, refractory, etc. the bulk of world bauxite production (approximately 85%) is used as feed for the manufacture of alumina via a wet chemical caustic leach method commonly known as the bayer process. subsequently, the majority of the resulting alumina produced from this refining process is in turn employed as the feedstock for the production of aluminum metal by the electrolytic reduction of alumina in a molten bath of natural or synthetic cryolite (na3alf6), the hall-héroult process.
