Abstract (en)
[origin: EP2226307A1] A procedure for enhancing clays so that they can be used in ceramic products to increase the content of clayey material, to remove the unwanted large particles, to increase the whiteness of the clays after baking and to reduce the percentage of defects after baking comprising the steps of obtaining an aqueous suspension of clay; removing of the fraction greater than 60 µm using physical separation procedures; classifying of the clay in suspension on the basis of the particle size, using mechanical means; treating of the fraction with the smallest particle size; removing the water in the suspension in order to obtain the cake; and washing the cake with water in order to reduce the content of soluble salts, such as sulphates and carbonates, before draining.
