Title: A process for the recovery of value metals from base metal sulfide ores
Inventor: SRIDHAR RAMAMRITHAM
IPC: C22B23/00
Filed: 2004-09-27
Abstract: A process for leaching a value metal from a base metal sulfide ore, comprising the step of leaching the ore with a lixiviant comprising a chloride, an oxidant and hydrochloric acid is disclosed. The leaching is controlled, by use of low concentrations of hydrochloric acid and a redox potential, to effect formation of hydrogen sulfide from the base metal sulfide ore. The hydrogen sulfide is stripped from the leach solution, thereby reducing the amount of sulfate generated in the leach to very low levels. The leaching may also be conducted to limit the co-dissolution of platinum group metals and gold with the base value metals. The leach forms a value metal-rich leachate and a solids residue. The solids residue may be subsequently leached to recover the platinum group metals and gold. The value metal-rich leachate can be oxidized and neutralized to recover the value base metals. In an embodiment, the chloride is magnesium chloride and lixiviant solution is regenerated.

Patent CA-2487135-A1 (CA)
Inventor: RAKOV SERGEY
IPC: H01J49/42
Filed: 2003-05-30
Abstract: L'invention concerne un appareil et des procédés qui permettent l'interaction d'électrons à faible énergie et de positrons ayant des ions d'échantillonnage qui facilitent la dissociation à capture d'électrons (ECD) et la dissociation à capture de positrons (PCD), respectivement, dans les structures de guidage d'ions multipôle. Il a été découvert récemment que la fragmentation d'ions protonés de plusieurs biomolécules par dissociation à capture d'électrons se produit le long de chemins de fragmentation auxquels d'autres procédés de dissociation n'ont pas accès. Ces chemins mènent à des informations de structure moléculaire qui ne sont pas si faciles à obtenir autrement. Cependant, de telles analyses ont été limitées aux spectromètres de masse à résonance cyclotronique ionique à haut champ et transformée de Fourrier (FTICR) onéreux. La mise en oeuvre de la dissociation de capture d'électrons (ECD) dans des structures de guidage d'ions multipôles utilisées couramment est problématique dû aux effets perturbateurs de champs RF dans ces dispositifs. L'appareil et les procédés décrits surmontent ces difficultés, et permettent d'exécuter la dissociation à capture d'électrons (et dissociation à capture de positrons) dans les guides d'ions multipôles, soit tout seuls, soit combinés aux procédés de fragmentation d'ions conventionnels. L'invention concerne donc l'exécution analytique améliorée et la fonctionnalité de spectromètres de masse qui utilisent des guides d'ions multipôles.

Abstract: A novel drill for the aerification of turf grasses is disclosed. The drill comprises a chuck and a fluted turf drill bit (10) held by the chuck. The chuck includes a locking mechanism which permits the chuck to rotate freely about its longitudinal axis when loaded in compression (as when the drill is inserted into the ground) but which locks, preventing rotation, when the drill is loaded in tension (such as when the drill is withdrawn from the soil). The drill bit (10) has a smooth upper section and a fluted lower section. The smooth section decreases the probability of entangling the turf in the drill bit (10) with subsequent lifting of the turf when the drill is withdrawn. The tip of the drill bit (10) is adapted to provide a torque to the drill bit (10) during insertion into the ground.
