Patent CA-2879481-C (CA)
Inventor: NISBETT ANDREW
IPC: C22B15/00
Filed: 2013-08-07
Granted: 2017-01-24
Abstract: The present invention relates to a metal leach and recovery process. The process involves subjecting a metal bearing material to a reactive process by combining said metal bearing material with a leaching agent to liberate at least one metal value and forming a first aqueous leach pulp. This first aqueous leach pulp is subjected to a solid liquid separation step thereby providing a first clarified aqueous leach solution and a second aqueous leach pulp. The first clarified aqueous leach solution is then subjected to solvent extraction thereby obtaining the first aqueous raffinate. The second aqueous leach pulp is subjected to at least two further solid liquid separation steps of which some or all are in a counter current decantation (CCD) arrangement. Each of the solid liquid separation steps of the CCD arrangement results in an aqueous liquor and aqueous suspension of solids wherein each aqueous suspension of solids resulting from each solid liquid separation step of the CCD arrangement is passed to the subsequent solid liquid separation step and the suspension of solids resulting from the final solid liquid separation step is removed from the process. Further, each aqueous liquor resulting from each solid liquid separation step of the CCD arrangement is passed to the previous solid liquid separation step. The further solid liquid separation steps result in at least one further clarified aqueous leach solution. The at least one further clarified aqueous leach solution is/are subjected to solvent extraction thereby obtaining at least one further aqueous raffinate. At least a portion of the one or more of the at least one further aqueous raffinates is fed into the final solid liquid separation is of the CCD arrangement. The process provides a flocculation system comprising either: (i) addition of an organic polymeric flocculant to or prior to at least one solid liquid separation step, which polymeric flocculant is formed from 2-acrylamido-2-methylpropane sulphonic acid (ATBS) or salts thereof as a homopolymer or copolymer with at least one water-soluble ethylenically unsaturated monomer; or (ii) addition of an organic polymeric flocculant and at least one support agent to or prior to at least one solid liquid separation step, which at least one support agent is selected from at least one of the group consisting of oxidising agents, reducing agents, irradiation and free radical producing agents. The process provides significantly improved metal extraction and recovery.

Abstract: Selon divers modes de réalisation, la présente invention concerne des fibres de pâte à papier à surface aggrandie, divers produits comprenant lesdites fibres, ainsi que des procédés et des systèmes de fabrication de fibres de pâte à papier à surface aggrandie. Divers modes de réalisation de fibres de pâte à papier à surface aggrandie ont des surfaces spécifiques considérablement plus grandes par comparaison avec des fibres raffinées classiques, tout en réduisant à un minimum avantageusement des réductions de longueur à la suite du raffinage. Les fibres de pâte à papier à surface aggrandie peuvent être comprises dans un grand nombre de produits qui peuvent tirer avantage de telles propriétés comprenant, par exemple, des produits de papier, des produits de carton, des panneaux de fibrociment, des matières plastiques renforcées par des fibres, des pâtes en flocons, des hydrogels, des produits d'acétate de cellulose et des produits de carboxyméthylcellulose. Dans certains modes de réalisation, une pluralité de fibres de pâte à papier à surface aggrandie ont une longueur de fibre moyenne pondérée d'au moins environ 0,3 millimètre et une surface spécifique hydrodynamique moyenne d'au moins environ 10 mètres carré par gramme, le nombre de fibres de pâte à papier à surface aggrandie étant d'au moins 12 000 fibres/milligramme par rapport au produit séché en étuve.

Abstract: A method for centrifugal casting using a sand core having a refractory coating applied in a dry state, without the use of a liquid carrier, said coating sufficient to withstand the adverse forces of the centrifugal casting environment and yield a finished cast surface with a consistent, smooth surface. The coating may be applied by pressing the coating into a mixture of refractory material and impacting media fluidized in a vibratory bed such that the core floats in the mixture, and then rotating the core to coat the surfaces that will be in contact with the molten metal in the casting process.

Abstract: An electric ratchet wrench includes a driving member (21) rotatably mounted in a body (10). A pawl device (22) is pivotably mounted to the driving member (21). A ring gear (23) is rotatably mounted around the driving member (21). An elastic device (30, 30a) is mounted between the ring gear (23) and the driving member (21). A transmission shaft (51) includes a first end connected to a motor (41) and a second end configured to switch between a meshing state meshed with the ring gear (23) and a disengagement state disengaging from the ring gear (23). The motor (41) drives the transmission shaft (51) to rotate the driving member (21). The body (10) can be manually driven to overcome a resistance which is larger than the torque outputted by the motor (41) and which causes a tooth slippage phenomenon between the transmission shaft (51) and the ring gear (23).
