    摘要： A first objective of the present invention is a method for dry milling material which contains carbonate ore, characterized in that the said method comprises the following steps: a) dry milling of the said material in at least one milling unit: (i) in the presence of at least one polyalkylene glycol polymer where at least 90% but preferably 95% at least, and very preferably 98% at least of the monomer units forming the backbone of the said polymer are constituted by ethylene oxide, propylene oxide or their mixtures, and where the molecular weight is at least equal to 400 g/mole, (ii) such that the quantity of water in the said milling unit is less than 10% in dry weight of the said material in the said milling unit; b) the milled material may then be classified according to step a) with at least one classification unit; c) the steps a) and/or b) may be repeated with all or part of the milled material from step a) and/or step b). Another aim of the present invention is a product coming from step a) and/or b) and/or c) of the method of the invention. A third object of the present invention is the use of the said product from step a) and/or b) and/or c) for making sealant, paper, paint, plastic or else for formula used in agriculture.

    摘要： The present invention relates to the use of surface modified calcium carbonate as a filler in adhesives, sealants, and/or caulks, wherein the surface modified calcium carbonate is a mineral pigment product formed in situ by the double and/or multiple reaction between a calcium carbonate and the reaction product or products of the said carbonate with gaseous CO2 formed in situ and/or coming from an external supply, and the reaction product or products of the said carbonate with one or more moderately strong to strong H3O+ ion donors, and at least one aluminum silicate and/or at least one synthetic silica and/or at least one calcium silicate and/or at least one silicate of a monovalent salt and/or at least one aluminum hydroxide and/or at least one sodium and/or potassium aluminate. It further relates to method of producing adhesives, sealants, and/or caulks comprising surface modified calcium carbonate, as well as to the adhesives, sealants, and/or caulks obtained by this process.
