Method for dry milling of materials which contain carbonate ore |
摘要 |
The present invention is directed to a method for dry milling a material containing a carbonate ore. The method comprises the following steps: (a) dry milling the material in at least one milling unit: (i) in the presence of at least one polyalkylene glycol polymer having monomer units forming a backbone, where at least 90% of the monomer units forming the backbone of the polymer are constituted by ethylene oxide, propylene oxide or their mixtures, and where the polymer has a molecular weight of at least equal to 400 g/mole, (ii) such that the milling unit contains a quantity of water that is less than 10% in dry weight of the material in the milling unit; (b) optionally classifying the material from step a) with at least one classification unit; and (c) optionally repeating steps a) and/or b) with all or part of the material from step a) and/or step b). |
