Abstract: Systems and methods of treating an inorganic particulate material with an antimicrobial agent are discussed, including: introducing the inorganic particulate material and water to an air swept dryer; introducing the antimicrobial agent to the air swept dryer; and at least partially drying, and optionally at least partially pulverizing, the inorganic particulate material in the presence of the antimicrobial agent forming a treated inorganic particulate material, wherein at least a portion of the antimicrobial agent is exchanged onto and/or into the surface of the treated inorganic particulate material.
