PURPOSE: To obtain coated talc having excellent dispersibility, pigment characteristics, etc., by dispersing calcined talc in an aq. soln. of a water-soluble hydrolyzable metallic compd. to precipitate a metal oxide or hydroxide over the entire surface of the talc particle and achieve uniform coating.

CONSTITUTION: An aq. soln. of a water-soluble hydrolyzable metallic compd. such as titanium sulfate, aluminum chloride, zinc sulfate, ferrous sulfate, cobalt chloride or sodium silicate is prepd. Calcined talc which has been calcined at 500W950°C, is dispersed in this soln. to precipitate a metal hydroxide and/or a metal oxide over the entire surface of the talc particle. The coated talc is recovered by filtration and optionally calcined to obtain coated talc whose surface is completely coated with the metal hydroxide and/or the metal oxide and which is colored, in a desired color such as black, red, yellow, green or blue.
