  • Integrated ammoniacal solvent extraction and hydrogen reduction of nickel
    Patent number: 7357827
    Abstract: A process is provided for the recovery of a metallic nickel product in a solvent extraction process which includes the steps of forming a nickel ammine complex by stripping nickel from a nickel loaded organic phase with a high strength ammonia solution and then reducing the nickel ammine complex with hydrogen from the high strength ammonia solution to produce a metallic nickel product. By virtue of the present process, a reductive precipitation of nickel by hydrogen is obtained so as to recover a metallic nickel product, and the process is advantageous in that it will allow for commercial processes wherein nickel may be recovered by hydrogen reduction based on high strength ammonia solutions.

  • Data Communication in Electronic Blasting Systems
    Publication number: 20080041261
    Abstract: Wireless blasting systems present significant technical challenges. Discloses herein are blasting apparatuses, and methods for their use, that employ a network of blasting machines and detonators, each detonator capable of wireless communication not only with the blasting machines, but also with other detonators, so that those detonators (and associated components) that are “blind” to communication with the blasting machines can remain functional in the blasting network. Importantly, the wireless signal receiving, processing and transmitting means associated with each detonator is powered by a supply insufficient to cause inadvertent detonator initiation unless a specific FIRE signal is transmitted by a blasting machine, and received by the detonator.

  • Collapsible Container
    Publication number: 20080029510
    Abstract: A collapsible container includes a base, a top, and opposed side covers arranged between the base and the top. The side covers have a lower section frame pivotally connected to the base and a top section frame pivotally connected to the top, and a central hinge arrangement configured so that the top section frame is pivotally movable relative to the lower section frame. The side covers can thus be selectively positioned between an erected position and a collapsed position. In the erected position, the container presents an interior space. End covers are arranged to be pivotally movable between an upright position for covering respective open ends, and a down position for allowing the side covers to be movable to the collapsed position.
