Abstract
A process for preparing concentrated slurries of TiO.sub.2 and water with a solids content of 30-70% by weight from TiO.sub.2 micronizer tailings that are carried in steam separated from TiO.sub.2 and steam from a micronizer by scrubbing the steam and TiO.sub.2 micronizer tailings with a slurry of TiO.sub.2 and water, separating TiO.sub.2 and water from the steam and circulating a portion of the TiO.sub.2 and water to the absorber until the solids content desired is reached.
