Abstract: A method for segregating bark and/or foliage from wood chips and/or twigs in a mixture of such components is provided. The method includes three essential steps. The first step comprises conditioning a pile of such mixture by periodically sprinkling the pile with water during storage. The second step comprises vigorously agitating the conditioned mixture with sufficient water, and for sufficient time to break bonded bark from the wood chips and the twigs and to comminute the bark. The third step comprises wet screening the agitated mixture thereby separating effluent bark and foliage from the wood chips and/or twigs in the mixture. An additional step includes dewatering the effluent bark and foliage, thereby to recover screened out solids materials. This method can be operated successfully on either a batch or a continuous basis without any serious effect on the reduction of pulp quality.
