Disclosed is a process for preparing fine-particle carbon black-filled rubber powder grains from a rubber-latex emulsion and carbon black by precipitation. The process avoids use of a water soluble salt of a metal of Group IIa, IIb, IIIa or VIII of the Periodic Table of the Elements and an alkali metal silicate. The precipitation is conducted by mixing the rubber-latex emulsion with an aqueous suspension of a portion of the carbon black while adding a Bronsted acid (e.g. H2SO4) either before or after the mixing and later adding an aqueous suspension of the remaining portion of the carbon black.
