  • Patent number: 4523993
    Abstract: By providing an open-ended perforate vessel which is rotatable about its central axis and incorporates a removable filter element, a highly efficient easily employable precious metal recovery apparatus is achieved capable of removing precious metal from an aqueous carrier. Preferably, the perforate vessel is supportingly contained within a housing which receives the aqueous carrier after passage through the filter and delivers the aqueous carrier to a disposed area. In addition, the perforate vessel is preferably cylindrically shaped with holes formed throughout and the filter comprises a bag-like or envelope-like construction which is easily mounted about the walls of the vessel as well as easily sealed after filtration with the precious metal contained therein for delivery to a reclamation center.

  • Patent number: 4371436
    Abstract: Apparatus for recovering silver from spent photographic solutions comprises a tray with a number of non-reactive filter elements having successively smaller porosity through which the spent solutions can be passed. Each successive filter element prevents silver particles of progressively smaller sizes suspended in the liquid from passig therethrough. The filters are stacked in a horizontal position within the tray and a tray cover sits on top of the tray, the cover having an opening into which the developing solutions can be poured. The tray includes a drainage port which allows liquid passing through the filters to drain out of the tray.
