Abstract
A process for the separation of carbon black from liquids containing it is disclosed wherein a particular amount of a liquid hydrocarbon is added to the liquid containing carbon black to form a mixture whereby the carbon black passes into the hydrocarbon phase. The mixture is then passed to a settling zone and the hydrocarbon and carbon black are separated from the liquid by forming a layer thereon. The layer is then passed through a disk centrifuge to substantially separate the carbon black from the hydrocarbon.
