Minerios Ouro Branco Magnesium Silicate is known as talc, a mineral of inorganic constitution, chemically inert, extracted from deposits and processed in different granulometric ranges according to the desired application. It is presented in lamellar crystalline form, giving the mineral softness to the touch. Magnesium Silicate is White powder until slightly creamy or grayish, fine, odorless, insoluble in water.

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 Dolomite is a mineral of inorganic constitution, white powder, fine, odorless, insoluble and of low oil absorption, chemically inert, extracted from deposits and processed in several metric granule ranges according to the desired application. This cargo is widely used due to its low market value, due to the high demand and supply.

Minerios Ouro Branco Coated Calcium Carbonate is obtained from the surface treatment of natural calcium carbonate with calcium stearate or stearic acid, in order to lower abrasion and provide the material with a hydrophobic characteristic. Coated calcium carbonate is white, fine, odorless, insoluble, hydrophobic powder with low oil absorption.

Minerios Ouro Branco Precipitated Calcium Carbonate is chemically inert and is obtained by reacting a solution of calcium chloride with a solution of sodium carbonate, or by passing carbon dioxide through a suspension of lime milk. It is presented in medium, light and extra light types, differentiated only by granulometry, with the medium being the thickest and the extra light being the finest. Precipitated Calcium Carbonate is white, fine, odorless, insoluble, light, porous powder with high oil absorption.

Minerios Ouro Branco Quartz is a mineral of inorganic constitution, chemically inert, extracted from deposits and processed in different granulometric ranges according to the desired application. It is presented in hexagonal crystalline form. Quartz or natural crystalline silica is white to slightly grayish powder or granules, odorless, insoluble in water, low oil absorption and abrasive.

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.

Minerios Ouro Branco Natural Calcium Carbonate, also known as calcite is a mineral of inorganic constitution, white powder, fine, odorless, insoluble and of low oil absorption, chemically inert, which is extracted from deposits and processed in different granulometric ranges according to the desired application. Cargo widely used due to the low market value, this due to the high demand and supply.
