Method and apparatus for screening

A screening apparatus, comprising:

• a static vertical screen basket having a grid structure;
• a plurality of screen assemblies, each screen assembly including a case and a screen, the plurality of screen assemblies being secured over grid openings of the grid structure, the screens of the plurality of screen assemblies forming a screening surface located on the outside of the screen basket;
• wherein the screening surface is configured to separate an oversized material from an undersized material by allowing undersized material to flow into the screen basket while preventing oversize material from entering the screen basket,
• wherein each screen has a synthetic screening surface having openings having sizes in a range from approximately 35 microns to approximately 4,000 microns, and
• wherein each synthetic screening surface is configured to separate carbon or resin from a slurry of carbon-in-leach (CIL), carbon-in-pulp (CIP) or resin-in-leach (RIL) material as fluid of the slurry flows from outside the grid structure to inside the grid structure due, at least in part, to a static pressure differential between fluid outside relative to fluid inside the grid structure such that carbon or resin is retained on the synthetic screening surface.
