Abstract

Oppfinnelsen vedrører en fremgangsmåte ved behandling av rejekt fra et anlegg for avsverting av avfallspapir, hvilket rejekt omfatter en blanding av trykkfarvepartik-ler, uorganiske partikler og fibre, hvilken fremgangs-. måte innbefatter trinnet å danne en vandig suspensjon eller oppslemming omfattende rejektet og et utfelling av et i det vesentlige hvitt, uoppløselig salt som inn-. fanger eller aggregerer trykkfarvepartiklene, uorganiske partikler og fibre inneholdt i rejektet, hvorved den mørke farve av rejektet gjøres lysere ved dannelse av utfellingen. Utfellingen kan omfatte kalsiumkarbonat. ; dannet ved å omsette karbondioksyd med kalsiumhydroksyd. i suspensjonen. Utfellingen og innfanget el]er aggregert materiale deri kan separeres for nyanvendelse som par-. i tikkelformig belegnings- eller fyllstoffmateriale. Pro-. j duktet kan separeres fra vann, som etter separasjon er I klarere enn etter opprinnelig behandling, og dette vann resirkuleres for nyanvendelse. Rejektet kan være en j oppslemming eller et slam fra en fIotasjonsprosess i et i avfallspapir-avsvertingsanlegg.i
