20120269672 | METHOD FOR MANUFACTURING A METAL INGOT COMPRISING A BORE, AND ASSOCIATED INGOT AND MOLDING DEVICE - In said method, the mold ( | 10-25-2012 |
20150013931 | MOLDING DEVICE FOR A METAL INGOT COMPRISING A BORE - A molding device for vacuum casting a metal ingot is provided. The mold includes a mold cavity defined by an ingot mold, a core and a bottom. The mold is arranged inside a vacuum-cast enclosure and includes a source of introducing molten metal at the upper portion thereof. A distribution device for receiving and distributing molten metal, which is suitable for receiving the molten steel introduced into the vacuum-cast enclosure and for redistributing the molten metal in the mold cavity, is arranged at the upper portion of the mold cavity. The molten metal is introduced into the enclosure so as to form a first jet of molten steel under a vacuum, in order to pour the molten metal over the distribution device and to form at least one second jet of molten steel under a vacuum, which originates with the distribution device and terminates in the mold cavity so as to fill the mold cavity with molten metal. | 01-15-2015 |

20120070351 | METHOD FOR RECOVERING RARE-EARTH ELEMENTS FROM A SOLID MIXTURE CONTAINING A HALOPHOSPHATE AND A COMPOUND OF ONE OR MORE RARE-EARTH ELEMENTS - A method is described for recovering rare earth elements from a solid mixture including a halophosphate and at least one compound of one or more rare earth elements. The method includes: (a) acid etching the mixture; (b) adding a base to bring the pH back up to a value of at least 1.5; (c) etching the solid from step (b) with a solution of soda or potash; (d) acid etching the solid from step (c) until a pH of less than 7 is obtained, resulting in a solid phase and a liquid phase including at least one rare earth salt, and separating the solid phase from the liquid phase. | 03-22-2012 |
20140023571 | METHOD OF RECOVERING RARE EARTHS FROM A SOLID MIXTURE CONTAINING A HALOPHOSPHATE AND A RARE EARTH COMPOUND AND SOLID MIXTURES SUITABLE FOR THIS METHOD - An acid treatment, in a liquid medium, of a solid containing a halophosphate and a rare earth compound is described. Further described, is the addition of a base to the medium obtained previously and separation of a solid phase from a liquid phase; mixing and calcination of the solid obtained previously with an alkaline solid compound; redispersing the calcined product in water, separation of the solid product from the suspension obtained in the preceding step; dispersing this solid in water and acidification of the dispersion and separation of the solid from this dispersion. | 01-23-2014 |
