A method for separating and recovering ultrafine particulate solid material from a suspension or slurry of the solid material and a hydrocarbon liquid by precipitation or flocculation of a heavy fraction of the hydrocarbon liquid with an effective amount of a precipitation or flocculation agent such that the precipitated heavy fraction encapsulates the particulate solid material. The method further comprises coking the precipitated heavy fraction and grinding the coked product to an ultrafine size.
L'invention concerne un procédé pour séparer et récupérer un matériau solide particulaire ultrafin à partir d'une suspension ou d'une boue du matériau solide et d'un hydrocarbure liquide par la précipitation ou la floculation d'une fraction lourde de l'hydrocarbure liquide à l'aide d'une quantité efficace d'un agent de précipitation ou de floculation, de sorte que la partie lourde précipitée encapsule le matériau solide particulaire. Le procédé comporte de plus la cokéfaction de la fraction lourde précipitée, et le broyage du produit cokéfié jusqu'à une dimension ultrafine.
