Реферат: Methods and apparatuses for screening are provided. Embodiments include a screen basket apparatus for screening carbon-in-pulp (CIP), carbon-in-leach (CIL), or resin-in-leach (RIL) material so as to retain carbon or resin on an external surface of the screen basket. The screen basket comprises a grid frame having a plurality of openings arranged in a lattice and a plurality of screening cartridge assemblies affixed to the grid frame to cover the respective openings of the grid frame. The screening cartridge assembly includes a case and a screen assembly fitted into the case, and may be affixed to a set of transversal member of the grid frame. The case may be an injection molded thermoplastic, polyurethane or a thermoset polymer. The screening elements together form a generally continuous screening surface across an exterior portion of the grid frame. The use of polyurethane or thermoplastic material for the screens is more durable and alleviates blinding of the openings during operation compared to wedge wire screens in the prior art.
