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. Se explica sistemas y métodos para tratar un material particulado inorgánico con un agente antimicrobiano, que incluye: introducir el material particulado inorgánico y agua a un secador de barrido de aire; introducir el agente antimicrobiano al secador de barrido de aire; 5 y secar, al menos, parcialmente, y opcionalmente pulverizar, al menos parcialmente, el material particulado inorgánico en presencia del agente antimicrobiano que forma un material particulado inorgánico tratado, en donde al menos una porción del agente antimicrobiano es intercambiado sobre y/o hacia la superficie del material particulado inorgánico tratado.
