Chrome ore  - Chemical composition Cr2O3 and FeO – ore used in the production of chromium metal, ferro-chrome, foundry moulding sands, refractories, green glass, chromic acids. Available in the form of lumps, powder, sand, raw or processed into various sizes. Also called “Chromite”. To find out more about chromite ore, click here.

Zircon  - Chemical composition ZrO2 + HfO2 + SiO2 – comes chiefly from natural beach sands, having refractory properties it is mainly used in ceramics (as opacifier), firebricks for glass industry, and mold facing sand in foundries. To find outmore about zircon, click here.

Wollastonite  - Chemical composition SiO2 + CaO – natural calcium metasilicate with acicular structure with particular aspect ratios making it suitable for substitute of asbestos in fibre cement. Wollastonite is non-carcinogenic. Main applications are in plastics and polymers as a reinforcing agent, and in paints as a white filler, as well as in ceramic bodies, frits and glazes due to its whiteness resulting from its pure chemical composition and its combined calcium and silica. It is resistant to fire and an excellent insulating material. It also finds large volume applications in casting powders for the metallurgy. To find out more about wollastonite, click here.

Kaolin  - Chemical composition Al2O3 + SiO2 + H2O – pure natural form of hydrated aluminium-silicate clay – also called “China clay” – main uses are manufacturing of ceramic bodies, chinaware, sanitary ware, porcelain, electric insulators and filler in pigments and paints. Kaolin is also used as a coating and filling agent in paper. To find out more about kaolin, click here.
