Title: Process for solubilizing vanadium and optionally for obtaining ammonium metavanadate or v o
IPC: C01G31/00
Filed: 1964-04-06
Abstract: Vanadium as alkali metal vanadate is recovered from vanadium bearing materials comprising slags, ores and residues by oxidizing a melt of the material, an alkali metal carbonate and an alkali metal chloride having weight ratio 1 : 1 : 0.5 to 1 : 0.5 : 1 respectively, with air or oxygen at above 400 DEG  C., say between 600 DEG  and 700 DEG  C., and extracting alkali metal vanadate with, say, water.  The oxidizing agent may be air, oxygen, or solid oxidant such as a chlorate, nitrate or peroxide.  The melting can be effected by direct or indirect heating. Silica may be added to the material to be reacted. One part slag is crushed, mixed with 1 part sodium carbonate and 0.5 part sodium chloride, and melted in a rotary furnace by an oxidizing flame.  Air is blown over the melt at 650 DEG  C. for 30 minutes, and sodium vanadate extracted by stirring the melt in water at 80 DEG  to 90 DEG  C. in an iron vessel. The sodium vanadate solution may be adjusted to pH 3 to 7 e.g. 6.5, with a mineral acid and ammonium metavanadate precipitated by adding the ammonium salt of the acid employed at 80 DEG  to 90 DEG  C., maintaining said temperature for 1 hour before cooling.  The salt may be separated, washed with cold water, the washings being returned to the iron dissolving vessel, dried and decomposed at above 300 DEG  C., e.g. 450 DEG  C., to powdered or at 700 DEG  C. to molten vanadium pentoxide.

Fig. 1 shows an apparatus comprising a tank 10 from which a ribbon of thermoplastic material 14 is drawn by rollers 15, the ribbon being flattened, whilst it is setting, by rapidly-reciprocating hollow cooled platens 16.  The platens are carried by sliding brackets 20 which are reciprocated by cranked shafts 22.  In another arrangement (Fig. 4, not shown) the feed is vertically downwardly from the tank and the ribbon, after having been pressed between vertically-arranged cooled reciprocating platens, is bent around a roll and carried away horizontally. Fig. 5 shows two curved platens, the platen 51 being stationary and the platen 50 being reciprocated by an eccentric 55; or both of these platens may reciprocate.  If the material to be sheeted is thermosetting, the platens are heated.  The platens may be of thin metal reinforced internally by struts.  The Specification as open to inspection under Sect. 91 describes also the production of sheets, and states that continuous prisms may be formed on one face of the ribbon by using a platen 441, Fig. 7 (Cancelled), having a suitably-shaped forming surface 46; and that the arrangement shown in Fig. 5 (Cancelled) may be used, in which molten material 38 passes under a control gate 39, between sheeting rolls 41, 42, over rolls 43 and between horizontally-arranged reciprocating platens 44, 441.

Abstract: 692,718. Discharge apparatus. FERRANTI, Ltd. June 18, 1951 [June 16, 1950], No. 15023/50. Class 39(i) The external anode 30 of a thermionic discharge tube has an indented collar 32 against which is located a ceramic ring 34 through which passes a further conductive cylinder 33; the clearance spaces between the ceramic ring and each metallic cylinder are closed by fused glass 47 or other sealing material which is sufficiently viscous in the molten state for it not to be sucked through into the interior of the valve even when the latter is exhausted. Thus during processing, the outgassing temperature may be raised above the fusing temperature of the glass seals; it is stated that as high as 900‹C the molten glass will be too viscous to be sucked completely through a clearance space of .002 in. The inner cylinder 33 supports the grid 33<SP>1</SP>, and has a shoulder 36 bearing against ceramic ring 34. The construction applied to cylinder 30 is also applied to cylinder 33; thus it also has an indented collar 37 against which is located a ceramic plug 43 through which passes the cathode leads 42, 45, the clearance spaces being sealed by fused glass 46 as before. Fig. 1 (not shown) is a simpler tube construction in which the above sealing technique is applied to a cold-cathode gas-filled diode in which the outer metallic envelope forms the cathode.
