Title:
APPARATUS AND PROCESS FOR RECOVERY OF METAL VALUES FROM LEACH OR WASTE SLURRIES
Document Type and Number:
WIPO Patent Application WO2006030279
Kind Code:
A3
Abstract:
A process and apparatus for continuously stripping or recovering values from a value bearing material, typically a slurry or solution thereof. The resin and value bearing material are contacted in a counter-current manner (242, 246) in a contact zone (254, 220, 222) to load the resin with values from the value bearing material. The resin is fluidised by the value bearing material in the contact zone. The loaded resin is passed through a first washing zone (256, 224) to displace excess value bearing material. The loaded resin then passes through a stripping zone (258, 228, 226), typically an acid or alkali, to strip the values from the resin and form an eluate, which is treated further to recover the values. The stripped resin is washed in a second washing zone (260, 230), to displace excess stripping agent, and returned to the contact zone.
