The present invention is directed to silicon carbide whisker recovery from a mixture of silicon carbide whiskers and carbonaceous silicon carbide particles. The invention involves shredding the mixture down to a specified size, dispersing the mixture in water to form an aqueous mixture, agitating the aqueous mixture, mixing the aqueous mixture with an immiscible organic solvent which is lighter than water, agitating the resulting water-organic solvent mixture, allowing the organic solvent and its contents to rise above the water and its contents, separating the two liquid phases into an organic solvent phase and an aqueous phase and, lastly, performing a solid-liquid separation on each of the two phases, thereby obtaining from the aqueous solution the desired silicon carbide whiskers and obtaining from the organic solvent solution a carbonaceous silicon carbide particle product.
