摘要： A process of leaching gold comprising the steps of: a) leaching copper from copper sulfide ore material that contains gold or contains silicate ore containing gold until the copper grade is reduced to 7.9 wt % or less; b) mixing the resulting material having a copper grade of 7.9 wt % or less with a gold leaching solution selected from the group consisting of a first solution containing chloride ions and ferric ions, and a second solution containing chloride ions and iron ions, the iron ions having been oxidized to trivalent ferric ions by air bubbled into the second solution; c) adjusting the pH of the gold leaching solution to 1.9 or less with stirring to leach at least gold in the material into the gold leaching solution by the oxidative activity of the ferric ions contained in the gold leaching solution, wherein the concentration of gold is reduced by selectively removing gold from part or all of the gold leaching solution during gold leaching. This process efficiently leaches at least copper and gold from a copper sulfide ore.

摘要： A refrigerant go-around passage is provided in a housing of a compressor. The passage takes in refrigerant discharged from a compression mechanism into the housing, makes the refrigerant go around an axial line of the compressor and finally returns the refrigerant to the discharge-port side of the housing while separating liquid contained in the refrigerant from the refrigerant by centrifugation or by centrifugation and collision. In the mid portion of the refrigerant go-around passage, a liquid returning port is provided for returning the separated liquid to the housing in such a manner that the liquid returning port has an orientation that has a component in a direction of gravity and that is deviated from a traveling direction of the refrigerant.
