摘要： 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.

摘要： A sieve tray column for stripping or recovering metal values from a metal value bearing material includes an elongate column body having an upper end and a lower end and a chamber defined therein. A plurality of spaced apart sieve trays are located within the chamber at intervals between the upper and lower ends. A first inlet is located intermediate the upper and lower ends of the column for introducing a value bearing material, such as a solution or slurry thereof, into the chamber, which value bearing material is arranged to flow in an upwards direction through successive trays towards the upper end. A second inlet is located at or adjacent the upper end of the column for introducing a resin into the chamber, which resin is fluidised by the upwardly moving value bearing material and caused to flow from one sieve tray to another successive sieve tray towards the lower end of the column. As the resin and the value bearing material contact each other in a counter current manner metal values from the value bearing material are absorbed onto the resin, which metal values can be recovered from the loaded resin.
