(57) The present invention relates to a method for producing a highly porous fine powdery slaked lime composition, comprising a fluidification step for forming said highly porous fine powdery slaked lime composition having an Alpine fluidity greater than 50 % and which is carried out in a dryer/grinder chosen from the group consisting of a pin-type dryer/grinder, a cage-type dryer/grinder, an instantaneous dryer/disagglomerator and a combination of these until the powdery slaked lime composition has a non-solid residual-phase content of less than or equal to 3.5 % by weight and greater than or equal to 0.3 % by weight, as well as the product obtained therefrom.
