The invention relates to a method for clarification of raw green liquor in a sedimentation tank. According to the invention is a part of dregs separated in the sedimentation tank recirculated back into the inflow of raw green liquor， and preferably after passing the dregs through at least one turbulence generator (30， 31) that could break up larger dregs particles into smaller dregs particles， and thus create larger total surface on the dregs particles， improving sedimentation rate in the sedimentation tank. In a preferred embodiment is the recirculated dregs added into the flow of raw green liquor before a flocculant is added into the flow of raw green liquor and mixed recirculated dregs.
