Abstract: A method of improving metal leach kinetics and recovery during atmospheric or substantially atmospheric leaching of a metal sulfide is disclosed. In some embodiments, the method may comprise the steps of: (a) producing a metal sulfide flotation concentrate; (b) processing the metal sulfide concentrate in a reductive activation circuit that operates at a first redox potential, to produce a reductively-activated metal sulfide concentrate; and, (c) subsequently processing the activated metal sulfide concentrate in an oxidative leach circuit to extract metal values. In some disclosed embodiments, reductive activation steps may be employed prior to oxidative leaching steps (including heap leap leaching or bio-leaching steps). In some embodiments, physico-chemical processing steps may be employed during reductive activation and/or oxidative leaching. Systems for practicing the aforementioned methods are also disclosed.

Abstract: A coupling unit of tubular overlapping conduits that are swivelly coupled to each other and are locked together by a spring loaded hook type rocker arm member centrally hinged upon a boss on the outer overlapping conduit. The rocker arm member has an inward hook at one end and an outward spring member guide push button on the opposite end. The hook end is normally maintained radially inward through an aperature in the outer conduit and the push button is normally positioned radially outward to protrude through an aperature in a protective cover closure bonnet. The hook end of the rocker arm member cooperates with a hook and groove formation on the inner conduit to lock the inner and outer conduits together.

Abstract: Self adjusting stair walkway with double side handrailing keyed and hinged to opposed side bar hinge linkage configurations that have steps hinge supported in a manner that upon the main side bars being swung in an arc about its support hinge the steps remain level for practical use as a safe self supporting stairway suitable for pedestrian traffic from seventy-five degrees below the horizontal to sixty degrees above the horizontal then folds to an essentially vertical compactness upon reaching ninety degrees above the horizontal to a standby position. Opposed side gears hydraulically driven are provided for safely swinging the level step stairs that will hydraulically lock the stairs in a desired inclination whereupon controllable opposed ratchet and pawl configurations can safely and additionally lock the stairs in the position.
