Patent CA-2929931-A1 (CA)
Inventor: HARRIS MICHAEL J
IPC: E21B43/247
Filed: 2014-11-06
Abstract: The presently disclosed technique provides a method for operating a valve in a wellbore by: applying a first fluid pressure to a bore of the valve; trapping the first fluid pressure in a portion of the valve; reducing the pressure in the bore of the valve to a second fluid pressure thereby creating a pressure differential between the portion of the valve and the bore of the valve; and opening the valve responsive to the pressure differential. The valve may employ a first piston disposed in the body to trap a first fluid pressure in a chamber to create a differential pressure across a second piston when a second fluid pressure is applied to open the valve to fluid flow therethrough. The valve and the method may be used to actuate another valve downhole.

Title: Method for recovering cyanide from a barren solution
Inventor: BANERJEE KASHI
IPC: C22B11/08
Filed: 2016-09-08
Abstract: A process is disclosed for recovering cyanide used to leach gold or silver from ore. In the course of leaching gold or silver from ore, a barren solution is generated. A portion of the barren solution containing sodium cyanide is recycled to the cyanidation proc ess while blowdown from the barren solution is subjected to pre-treatment, UV photodissociati on and pH adjustment. Ultimately, a volatile hydrocyanic acid is formed and is absorbed into a sodium hydroxide solution through the employment of a gas-filled membrane. This forms sodium cyanide that can be recycled and used in the cy anidation process to leach gold or silver from ore.

Inventor: GARDEN IAN
IPC: B05B15/00
Filed: 2015-04-07
Abstract: La présente invention concerne un filtre comprenant un tube s'étendant d'une première extrémité à une deuxième extrémité et ayant un alésage avec une aire de section transversale interne. Le tube comprend une entrée avec une aire de section transversale d'entrée qui est positionnée au travers de la première extrémité du tube. Le tube comprend aussi une sortie avec une aire de section transversale de sortie, l'aire de section transversale d'entrée étant inférieure à l'aire de section transversale de sortie, et donc des débris qui sont assez petits pour entrer par l'entrée auront tendance à ne pas bloquer la sortie, qui est plus grande. Le filtre comprend de plus une pluralité d'autres entrées, souvent des fentes, dans le tube entre l'extérieur de celui-ci et l'alésage. Dans un mode de réalisation préféré, la première extrémité peut être tronconique et particulièrement en forme de dôme. Cela contribue à diriger les débris vers l'extérieur du tube, où il est moins probable qu'ils soient aspirés dans le filtre et qu'ils risquent de bloquer celui-ci ou un composant en aval, tel qu'une buse. Le filtre peut être attaché à une tuyauterie et une buse.
