Abstract
Carbonaceous material such as carbon powder is coated with a carbonizable nder in a continuous process in which the carbon particles and the binder, preferably together with a solvent, are introduced continuously into a vessel in which a continuous stream of a liquid vehicle in which the binder is insoluble is likewise introduced. The coated particles are then separated from the liquid phase by decantation or filtration.
