Abstract

Keksintö koskee menetelmää kemiallisen massanvalmistusprosessin (3) kemiallisesta talteenottoprosessista (2) saatavan kalsiumpitoisen kiinteän sivuvirtamateriaalin (1) käsittelemiseksi. Menetelmä käsittää kalsiumpitoisen kiinteän sivuvirtamateriaalin käsittelemisen hapolla (4), niin että saadaan hapon kalsium- ja/tai magnesiumsuolan käsittävä liuos (5). Keksintö koskee lisäksi järjestelmää (14) kalsiumpitoisen kiinteän sivuvirtamateriaalin käsittelemiseksi ja menetelmällä saatavia tuotteita (5, 13).
