ABSTRACT:
A method for sorbing metal values from a slurry containing the same is disclosed. The slurry is advanced through a plurality of vessels arranged in series while countercurrently directing a sorbent through the vessels. Metal values are sorbed from the slurry in each of the vessels by mixing the pulp to achieve homogeneity with the pulp being maintained at a predetermined level in the vessel. A portion of the homogeneous pulp is directed into an interstage screening system disposed within the vessel and at least partially submerged beneath the predetermined pulp level, whereby the sorbent is separated from the slurry. The separated sorbent is primarily returned to the vessel while a portion of the sorbent is removed from the interstage screening system.
