Abstract

En industrielt gjennomførbar prosess for kvalitetsforbedring av titanholdige materialer omfatter: (i) en forbehandling for å gjore silisiumdioJcsydet tilgjengelig til de spesielle betingelser ved en etter-følgende utlutning, og (ii) en vandig utlutning i nærvær av en syre og hvis betingelser velges slik at silisiumdioksyd som går i oppløsning, ikke hydrolyseres eller presipiteres som et silikat. Forhandlingstrinnet (i) kan omfatte alkaliutlutning, røsting eller smelting.Utlutningstrinnet (ii) kan gjennomføres ved lave faststoff-densiteter.An industrially feasible process for improving the quality of titanium-containing materials comprises: (i) a pretreatment to make the silicon dioxide available to the particular conditions of a subsequent leaching, and (ii) an aqueous leaching in the presence of an acid and the conditions of which are selected so that silica that dissolves is not hydrolyzed or precipitated as a silicate. The negotiation step (i) may comprise alkali leaching, roasting or melting. The leaching step (ii) may be carried out at low solids densities.
