Abstract: 1,252,081. Extracting and purifying beryllium compounds. ANACONDA CO. 6 March, 1969 [6 March, 1968], No. 11939/69. Heading C1A. A process for extracting beryllium values from beryllium bearing material containing aluminium, iron, fluorine, zinc and other impurities by leaching with a mineral acid solution of pH 1À0 to 2À0 for a period sufficient to dissolve a substantial amount of the beryllium, the pH being maintained between 1À3 and 2. The solution obtained is suitably further treated by initially raising its pH to 3À0 to 4À5, causing precipita- 'tion of fluoro-compounds of aluminium and compounds of iron, separating the precipitates and then further raising the pH to 7À5 to 9À0 to precipitate beryllium hydroxide. A soluble fluoride may be added in the leaching step to improve the extraction of beryllium. A soluble sulphide may be added to the leach solution after the first pH raising step to precipitate zinc and other insoluble sulphides. The pH raising steps are suitably carried out using a base such as ammonia, alkali metal hydroxides, milk of lime or equivalent carbonates or oxides. The crude beryllium hydroxide precipitate may be purified either by (i) digestion in sodium hydroxide solution, followed by hydrolysis and reprecipitation, after 'optional further treatment with soluble sulphide or alternatively (ii) treatment with fuming sulphuric acid to give a precipitate of beryllium sulphate which is subsequently hydrolysed back to the hydroxide. In both of the above processes and also during the second pH raising step of the treatment of the leach liquor a further purification may be carried out by addition of a solution of a chelating agent, e.g. E.D.T.A., this preferably being carried out after sulphide treatment to eliminate those heavy metal ions whose chelates are not easily broken up for recovery of the chelating agent. The purified beryllium hydroxide is finally calcined to give the oxide.

The shaft 24 drives by an input race 30 an output race 60 drivingly connected to the rotary housing 12 axial loader balls 62 through rollers 70 on shaft 75 between torroidal surfaces 72, 74, The shafts 75 are mounted in bearings in carriers 77 and each has a U-shaped portion 120 with a ball end member 128 a pin extension 134 of which is engaged and held in an opening 136 of a lever 140 connected to a hub 98. The rotatable casing 12 has an end cover 14 and contains fluid which affects a pitot tube 144 connected by passages 152, 154 to a chamber 96 during rotation. Fluid pressure in the chamber 96 acts on a piston 80 slidable on the shaft 55 against the force of a spring 90. Control mechanism 78 to adjust the tilt of the roller 70 to maintain a constant output speed comprises a rotary link 102 on a pin 104 a leg 110 of which is engaged in a groove 84 in the piston 80 and an abutment 118 on another leg 112 which contacts the end of a shaft 75. In operation assuming a decrease in engine speed pressure delivered from the pitot 144 to the chamber 96 will decrease allowing piston 80 to be moved to the left, Fig. 1, by the spring 90. The movement of the groove 84 with the leg 110 pivots the link 102 counterclockwise and since abutment 118 cannot move the shaft 75 the link 102 moves down and by its pin 104 will rotate the levers 140 and thus the carriers 77  counterclockwise, Fig. 2, causing the shaft 75 with roller 70 to incline which inclination will cause tractive force between the rollers 70 and the races 30, 60 which has the effect of tilting the rollers 70 to increase the transmission speed thus restoring the speed of the output to its constant value and allowing the piston 80 to restore to its stable condition. In a modification in which a generator and power steering unit are contained in a single housing pressure from the pitot tube is applied to a spring- loaded piston acting parallel to the shaft of the rollers.
