Patent CA-2804180-A1 (CA)
Inventor: DIXON DAVID G
IPC: C22B15/00
Filed: 2011-06-28
Abstract: A method of recovering copper from chalcopyrite concentrate by chemical leaching, using pyrite and silver. The catalytic properties of pyrite in the chalcopyrite leaching process are significantly enhanced by pretreating the pyrite with silver ions. Particulate pyrite is exposed to a solution containing silver ions to form silver-treated pyrite. Particulate chalcopyrite and the silver-treated pyrite are mixed in an acidic sulfate leach solution. The copper is leached from the concentrate in the leach solution in the presence of an oxygen-containing gas, under conditions whereby the pyrite is substantially unoxidized. The leached copper is recovered from the solution by conventional methods. The used silver-treated pyrite is recycled to the leaching process.

Abstract: An audit system and method audits operation of an optmizer system in a mill, for example auditing operation of a cant optimizer which optimizes sawing patterns. The audit system may be completely independent of the optimizer. For example, the audit system may acquire information (e.g., optically) indicaitve of a geometry of boards downstream from a piece of equipment such as a gangsaw. The audit system may computationally reconstruct a cant from which the boards were sawn, determine an outside dimension indicative of wane, and simulate alternative sawing patterns, determining a theoretical amount of recovery that would have resulted from each and comparing such to actual recovery from the log or cant. Alternative sawing patterns may take into account various wane rules and comparision may take into account current demand and/or prices for dimensional lumber.

Abstract: The invention relates to a process for producing a methane-rich gas from synthesis gas. The starting point is a process in which a synthesis gas (4) comprising CO and H2 is mixed with a gas stream (8) branched off and recycled from the methane-rich product gas and is then conducted through a catalyst bed (1) of a methanization catalyst, methanization being effected in the catalyst bed (1) and the gas stream being heated by heat of reaction released. According to the invention, the catalyst bed (1) is divided between several methanization stages through which the flow passes successively (2.1 to 2.4) and the synthesis gas (4) is correspondingly divided into substreams (4.1 to 4.4), each of which is supplied to the catalyst bed (1) of an associated methanization stage (2.1 to 2.4). The gas (6.1 to 6.3) which leaves a methanization stage and is heated up by methanization reactions in this stage is mixed with the synthesis gas substream (4.2 to 4.4) for the downstream methanization stage and cooled at the same time. The resulting mixed gas stream is supplied to the catalyst bed of the downstream methanization stage as feed gas.
