Abstract

Menetelmä ja laitteisto hydrometallurgisessa prosessissa syntyvän ja pieniä määriä liukoisia raskasmetalleja sisältävän rautapitoisen sakan saattamiseksi stabiiliin muotoon neutralointiaineen avulla. Sakka lietetään ja lietetty sakka syötetään ainakin yhteen stabilointi- eli homogenointireaktoriin (3), jonne myös neutralointiaine johdetaan, ja sakan ja neutralointiaineen sekoitus toisiinsa homogeenisesti tapahtuu kierukkasekoittimen (8) avulla, jolloin sekoittimen halkaisijan suhde reaktorin halkaisijaan on 0,75 — 0,99.
