Filed: 1976-04-29
Abstract: 1517888 Recovery of Ti and Zr values MIZUSAWA KAGAKU KOGYO KK 29 April 1976 [1 May 1975 8 April 1976] 17544/76 Heading C1A Ti and Zr values are recovered from materials which also contain colouring poisonous metal components such as Mn, V and Cr by heating the material in a non reducing atmosphere at 750-950C in the presence of 2-5 times its weight of a flux composed mainly of an alkali metal nitrate or an alkali metal peroxide which is a thermal decomposition product of said nitrate to effect a fluxing reaction, leaching the flux reaction product in at least one stage with an aqueous medium to form a leach liquor containing said colouring metal components and a residue which is a concentrate of Ti and/or Zr metal which is acid soluble and substantially free of said colouring poisonous metal components. The flux material may contain 20-50% of an oxide, hydroxide, or nitrate of an alkaline earth metal. A portion of the leaching residue in an amount of at least 1À2 times the amount of raw material is preferably mixed with the raw material and flux, granulated and the resulting granular composition is heat treated according to the invention. Flux typically has a particle size of distribution such that 70% are between 0À1 and 2 mm. The leaching residue to be incorporated in the granules preferably has an oil absorption of at least 30 cc/100 g and average particle size not larger than 89 microns. The mixture is typically heated at 750-950C for 3 minutes-2 hours. A suitable leaching procedure employs cold water at 4-30C to dissolve out Mn and then an aqueous medium of pH 3-13 to dissolve out V and Cr. Metal values are recovered from both the leach liquor and the residue by conventional means. NO x  discharged from the fluxing heat treatment or various drying or decomposition steps may all be recovered as nitric acid or an alkali metal nitrate and recycled to the process. The alkali metal component contained in the fluxing reaction product can be substantially removed in the form of nitrate and recycled.

A method of pressure welding together a pair of members 1, 2 comprises placing those parts 5, 6 of the members to be welded together between a pair of tool surfaces, such as an aperture 4 in a die 3 and a surface 8 of a punch 7, and causing relative movement of the surfaces in a direction generally parallel thereto to bring them opposite one another and separated by a gap whose width gives the correct percentage reduction for cold pressure welding, whereby extrusion of material fiom between the two surfaces effects the welding. The method is applicable for cold welding parts of circular or oval cross-section such as a lid 2 on to a condenser can 1, both being made of aluminium. The mating surfaces of the parts 5, 6 are first cleaned by a rotary steel wire brush. As the welding surface 8 moves into the die aperture 4 the metal is extruded upwardly and out of the aperture and this excess metal is finally sheared off by a cutting edge 9. The article is subsequently ejected through the bottom of the aperture. Other embodiments are described for cold welding a brass tube into an aluminium plate, the cutting edge for removing excess metal being provided in the die, and for welding the axial conductors of squirrelcage rotors for induction motors.
