Abstract: A method is shown for the slaking of calcium oxides and magnesium from calcomagnesian compound containing at least 10 wt. % of MgO in relation to the total weight of said calcomagnesian compound, in which a slaking aqueous phase is supplied to a slaking device, and slaking the compound containing anhydrous dolomite delivered to the slaking device, by means of the slaking aqueous phase, forming hydrated solid particles of Mg(OH)2, in the presence of an additive.

Abstract: A method for reducing heavy metals, in particular in mercury, present in flue gases, includes the step of bringing the flue gases into contact with a particular class of sorbent material in the dry state. A preferred class of dry sorbent materials can be provided from a mineral compound selected from among halloysites and phyllosilicates of the palygorskite subgroup and the sepiolite subgroup of the palygorskite-sepiolite group according to the Dana classification. Mineral compounds of this group have been shown to provide a reduction in heavy metals, in particular in mercury, present in flue gases.

Abstract: Composition for treating and stabilizing soils, in particular wet soils, comprising, in the form of a powder having a particle size less than 5 mm, quicklime and/or calcium-based hydraulic binders, as well as a non-aqueous fluid additive capable of agglomerating the finer particles of the composition together.
