The pH may be greater than or equal to 6.5 and less than or equal to 8.5. Temperature may be greater than or equal to 100° C. and less than or equal to 160° C. Pressure may be greater than or equal to 150 kPa and less than or equal to 800 kPa.

Abstract: A locking twist pin screen panel retainer system utilizes a plurality of twist pins, each with a mushroom-shaped screen panel engaging head. Each one of the locking twist pins is positionable in a deformable receiver which is attachable to a support tube or bottom rail of a vibrating separatory machine. Insertion of the individual twist pins each into a cooperating one of the retainers, and the subsequent rotation of each twist pin through 90°, both secures the pin in the cooperating receiver and also secures the receiver in place on the underlying support tube or rail of the vibrating separatory machine. Removal of the pins and their receivers, if necessary, is accomplished by a further rotation of each pin through another 90°.

Abstract: The present invention relates to a process for recovering non-ferrous metals from a solid matrix comprising the following phases: (a) leaching the solid matrix with an aqueous-based solution containing chloride ions and ammonium ions and having a pH within the range of 6.5-8.5, in the presence of oxygen, at a temperature ranging from 100° C. to 160° C. and a pressure within the range of 150 kPa-800 kPa, so as to obtain an extraction solution comprising the leached metals and a solid leaching residue; (b) separating said solid leaching residue from said extraction solution; (c) subjecting said extraction solution to at least one cementation so as to recover the metals in the elemental state.

Abstract: A screen panel center retainer system for a vibrating separatory machine utilizes a center retainer that is provided with a retainer base which is adapted to be secured to screen stringer rails of a vibrating separatory machine. A pair of retainer channel legs form an upper portion of the center retainer and have screen panel edge receiving slots. A locking strip, having a wedging tongue, is used in conjunction with the center retainer. The wedging tongue is insertable into the channel on the center retainer which is defined by the two retainer channel legs. Flow control dams and cross dam retainers are used in conjunction with, and in addition to the center retainers and locking strips. The cross dam retainers are provided with locking strip end receiving pockets, to compensate for changes in the length of the locking strips. The screen panel center retainer system is configured to provide a functional, universal installation of screen panels on vibrating separating machines.

Abstract: A screen panel retainer assembly, that is utilizable with a vibrating separatory machine, is configured with a plurality of discrete, mushroom-shaped screen panel retainers. Each such retainer has a retainer head that is generally in the shape of a portion of a cylinder, such as a right cylinder. A shank connects each such retainer head to a suitable retainer bar. The retainer bar can be adapted to be attached either to screen stringer tubes of the vibrating separatory machine, or to underlying cross tubes and end cross tubes. The screen panels, which are to be secured to the vibrating separatory machine, have complementary shaped mushroom-shaped screen panel retainer head receiving chambers in their side surfaces. Two such panel edges define a whole chamber. The retainer heads are metal whereas the screen panel edges are resilient. The mushroom-shaped heads securely snap into their complementary chambers yet can be removed from those chambers when the screen panels have to be replaced.

Abstract: A snap lock separatory panel and retainer system includes either a screen wire panel with laterally spaced, longitudinally extending locking bars defining a locking profile, or a urethane panel with laterally spaced, longitudinally extending lips or flanges which also define a locking profile. A retainer system is provided for use in securing these panels. The retainer system utilized center retainers that are engagable with industry standard holes in screen stringer rails of a vibrating separating machine. Each center retainer is provided with an array of retainer pins which are spaced to interdigitate with either screen wire tie rod ends or with urethane panel wall recesses to support the screen panel locking bars or the urethane panel flanges adjacent the retainer pins. Locking strips are provided with undercurrent bores that terminate in undercut receptacles. These bores and receptacles are sized to receive center retainer pin shanks and heads.
