摘要： The invention relates to a method for reducing starch content of an aqueous phase, which is removed from a fibre stock preparation in a manufacturing process of paper, board, tissue or the like. The fibre stock preparation comprises a thickening step, where a fibre stock comprising cellulosic fibres originating from recycled fibre material and/or broke as well as starch dispersed in an aqueous phase is thickened from a first concentration to a second concentration by removing a part of the aqueous phase from the fibre stock. A cationic polymer obtained by copolymerisation of (meth)acrylamide and at least 25 mol-% of solely cationic monomer(s), having a standard viscosity SV of at least 1.7 mPas, is added to the fibre stock at the latest at the thickening step in order to associate the starch with the cellulosic fibres of the fibre stock.

摘要： The invention relates to a method for producing paper, board or the like. In the method is obtained an aqueous filler dispersion, comprising particles of at least one first filler, the filler dispersion having a floc size distribution with original mean chord length value. The particles of the first mineral filler are brought into a contact with a cationic pre-treatment agent, which is capable of initiating flocculation of the filler particles in the dispersion, whereby a pre-treated filler dispersion comprising flocs, which comprise first mineral particles, is formed. The pre-treated filler dispersion is combined with a stock of fibres. The floc size distribution of the filler dispersion is changed with the pre-treatment agent, which is a natural and/or synthetic polymer, so that the mean chord length value increases at least with 2 % from the original mean chord length value. The invention relates also to an agglomerate comprising at least one first mineral filler particle, a plurality of second mineral filler particles attached to at least one first filler particle by a pre-treatment agent, which is a natural and/or synthetic polymer. The average particle size by weight of the first mineral filler particles is 1.5 – 4.0 μm, the average particle size by weight of the second mineral filler particles is 0.5 – 2.4 μm, provided that the second mineral filler particles are smaller than the first mineral filler particles, and the mean chord length of the agglomerate is
