Minerios Ouro Branco Agalmatolite is a mineral of inorganic constitution basically composed of aluminum silicate, chemically inert, white powder until slightly creamy or grayish, fine, odorless, insoluble extracted from deposits and processed in different granulometric ranges according to the desired application. It is presented in lamellar crystalline form.

Minerios Ouro Branco Natural Kaolin is a mineral of inorganic constitution, white powder until slightly creamy, fine, odorless, insoluble, chemically inert, extracted from deposits and processed in different granulometric ranges according to the desired application. It is presented in lamellar crystalline form with an irregular surface, providing great adsorption power. It can be treated by chemical bleaching or by calcination leaving the product whiter.

Minerios Ouro Branco Calcined Kaolin 0B-2940 is a synthetically modified mineral, manufactured from the calcination of natural kaolin (aluminum silicate). After the calcination process, its crystalline form is modified due to the loss of crystalline water from the molecule, leaving the material whiter, more opaque and abrasive. Inorganic material, chemically inert and benefited in low granulometry.
