| titleOfInvention | METHOD FOR BLEACHING SURFACE OF AQUEOUS MINERAL SUSPENSION |
| abstract | 1. A method of whitening the surface of a suspension of mineral substances, characterized in that the method includes the following process steps: a) preparing by dispersing and / or grinding at least one aqueous mineral suspension, b) adding during and / or after stage a) 0.005 wt.% - 0.5 wt.% Based on the dry matter of at least one alkylene oxide block or random copolymer, preferably a block copolymer. 2. The method according to claim 1, when 0.005 wt.% - 5 wt.% Calculated on the dry matter of at least one dispersing agent and / or intensifier grinding is added during and / or after stage (a) and / or stage ( b) .3. The method according to claim 1 or 2, when at least one alkylene oxide block copolymer is a two- or three-block copolymer, preferably at least a three-block copolymer. The method according to claim 3, when the two-block copolymer is EO / PO, and the three-block copolymer is a block copolymer EO / PO / EO or block copolymer PO / EO / PO.5. The method according to claim 4, where the three-block copolymer has the general structure: (I) and where x, y and z can independently be any integer between or equal to 1 and 120, preferably between or equal to 1 and 80, more preferably between or equal to 3 and 70, even more preferably between or equal to 5 and 34, and where x and z are the same or different integers or (II) where a, b and c can independently be any integer between or equal to 1 and 120, preferably between or equal to 1 and 80, more preferably between or equal to 3 and 70, even more preferably between y or equal to 5 and 34, and wherein a and c - they are the same or different integers and wherein R and R 'in the formulas (I) - (II) - are alkyl residues and / or vodorod.6.
