Abstract

Un método de tratamiento de un material particulado que comprende partículas de un carbonato metálico alcalinotérreo, que incluye el paso deexponer el material particulado a una atmosfera de tratamiento que contiene un agente de tratamiento de superficie que comprende uno o más ácidos grasos, quereacciona y reviste las partículas del material particulado, en donde la atmosfera de tratamiento está sustancialmente libre de agua y se mantiene a unatemperatura que es superior al punto de fusion del agente de tratamiento de superficie, y por lo menos 120*C, con preferencia 125*C o más, y en donde enla atmosfera de tratamiento, la concentracion del agente de tratamiento de superficie y el tiempo de residencia del material particulado son tales demanera de proporcionar un revestimiento quimioadsorbido del agente de tratamiento de superficie en por lo menos 75%, con preferencia en por lo menos90% del área de superficie del material particulado, y la cantidad de agente de tratamiento de superficie fisioadsorbido o no reaccionado contenido en elmaterial particulado inmediatamente después de dejar la atmosfera de tratamiento no es mayor a aproximadamente 0,5% con preferencia 0,4% o menos, enpeso en base al peso seco del material particulado.A method of treating a particulate material comprising particles of an alkaline earth metal carbonate, which includes the step of exposing the particulate material to a treatment atmosphere containing a surface treating agent comprising one or more fatty acids, reacting and coating the particles of the particulate material, where the treatment atmosphere is substantially free of water and is maintained at a temperature that is higher than the melting point of the surface treatment agent, and at least 120 * C, preferably 125 * C or more , and where in the treatment atmosphere, the concentration of the surface treatment agent and the residence time of the particulate material are such as to provide a chemo-absorbed coating of the surface treatment agent at least 75%, preferably in at least 90% of the surface area of the particulate material, and the amount of treatment agent of physio-absorbed or unreacted surface content in the particulate material immediately after leaving the treatment atmosphere is not more than about 0.5%, preferably 0.4% or less, weight based on the dry weight of the particulate material.
