Abstract
L'invention concerne une charge comprenant des particules d'argile blanche ayant : a. Une distribution de dimension telle qu'elle ne contient pas plus de 18 % en poids de particules supérieures à 2 microns; b. Une abrasion inférieure à 120 Valley et c. Un brillant d'au moins 76. Selon l'invention, on soumet une argile blanche à une classification par dimension des particules à 2 étages, puis à un enrichissement et on élimine ou blanchit suffisamment d'impuretés contenant du fer. Application dans l'industrie papetière.
