Title: A method for the recovery of metallic and metal complex ions from a slurry containing the same
IPC: B01J47/10
Filed: 1961-06-22
Abstract: <PICT:0959227/C1/1> Metallic and metal complex ions are recovered from a slurry containing the same in insoluble form together with other insoluble materials by dissolving the metallic component contained in the slurry to form an ionic solution by the addition of a suitable solvent to the slurry; countercurrently contacting the thus treated slurry with an ion exchange resin capable of adsorbing the metallic or metal complex ion while agitating at such a speed that the upper and lower resin layers do not mix with each other and that no drifted flow occurs, the ion exchange reaction being carried out in a liquid passing vessel having a vertically suspended stirrer, and a hopper at its upper end for introducing ion exchange resin, a resin outlet at its lowermost part, a slurry inlet situated at its lower end but above the resin outlet and an outlet situated at its upper end for the overflow of treated slurry containing liquid; regenerating the resin having adsorbed the desired ions; and adding to the resulting solution containing said ions a precipitating agent for ions other than the desired ions and a flocculating agent to assist the precipitation.  Copper can be recovered from the slurry resulting from the spinning step for the production of cuprammonium rayon fibre by adding sulphuric acid to the waste water containing copper ions from the spinning step which is placed in vessel 4 (see the Figure) and then passing the resulting copper-containing weakly acidic liquid upwardly through the liquidpassing vessel 1 which contains a cation exchange resin in the ammonium form.  As the liquid ascends it is subjected to ion-exchange reaction with the resin which absorbs copper and other metal ions.  The resin then passes from outlet 11 to water washing vessel 2 which is filled with water introduced at 14 and the washed resin is then passed to regenerating vessel 3 via outlet 15 and hopper 16.  In the regenerating vessel the water-washed resin is countercurrently contacted with an aqueous solution of ammonium sulphate which is introduced at 17 and the regenerated resin ready for re-use is passed to hopper 10 of vessel 1 via outlet 18. Meanwhile the solution containing the desired ions overflows at the top of vessel 3 and is passed to purifying vessel 20 where it is treated with aqueous ammonia to convert the copper ions to tetramine copper sulphate while any other ions are precipitated. The mixture is passed to vessel 22 and a flocculating agent is added and as the precipitate formed deposits the copper to be recovered overflows as tetramine copper sulphate solution.  The precipitate 9 is passed into dissolving vessel 4 to be recycled to effect the complete recovery of copper. Metal complex ions such as sodium bichromate may also be recovered using anion-exchange resins.

An hydraulic jack comprises a hollow piston rod 46 connected to an annular piston 56, 58 working between inner and outer cylinders 24, 18 so as to provide working chambers 98, 100 and a retraction chamber 101. To extend the jack liquid is supplied to working chamber 98 if the piston is lightly loaded and to chambers 98, 100 if the load is greater. To extend the jack liquid is supplied through a line 105 and a duct 102 to chamber 98, and liquid in the retraction chamber 101 is expelled through a line 110 to an annular chamber 136 and thence part passes through ports 138, the space around a valve stem 150 and ports 134<SP>1</SP> into chamber 100 to maintain it filled as the piston rod moves outwardly; the rest of the liquid passes from the annular chamber 136 through ports 140 and a line 118 to exhaust. If the force on the piston is insufficient to move the load, the pressure in chamber 98 increases until a valve sleeve 144 is moved to the right against the action of a spring 152 and closes ports 134<SP>1</SP> and uncovers ports 134 so that liquid from line 105 is supplied through the ports 134 to chamber 100. To retract the jack liquid is supplied from line 118 through the line 110 to the retraction chamber 101 and the pressure acts on a valve member 156 which is moved to the left to block ports 138 and to unseat a valve head 148 from an internal seat in the valve sleeve 144 so that liquid from chamber 100 passes through ports 134<SP>1</SP> and past the unseated valve head 148 to join the liquid exhausted from chamber 98. The piston is formed by two annular sections 56, 58 screwed to a rod 46 and provided with chevron seals 66, 68, 72 and a wear-ring 70. The sections are locked to the rod by a tapered pin 74 passing through co-operating notches in the sections and an opening in the rod, the wearring 70 being rotated after insertion of the pin to move an aperture out of register with the pin. Piston section 58 is formed with a recess 94 and cylinder head 44 is formed with a projection 96 which enters the recess to cushion the end of an extension-stroke. The other cylinder head 10 houses the valve mechanism.

A disc brake comprises a pair of pressuremembers slidably mounted on a fixed support for independent motion parallel with the disc axis under the control of two levers pivoted to one of the pressure members. The members 12, 13 are slidably mounted on rods 14, 15, Fig. 3, secured to a frame 17 attached to a fixed support, the frame 17 and members 12, 13 being reinforced by ribs and bracing members. A pair of arched arms 20, 21 secured to member 12 and extending over the disc 10 to a position adjacent member 13, carry a lever 23 pivoted at 59 between the free arm ends, the lever 23 having a portion 69, Fig. 6, extending transversely of the disc and having an inner edge 70 resting on a roller 22 carried on one side of an actuating lever 19 pivoted at 73 between the base portions of arms 20, 21. The lever 23 has an end portion 65 carrying a screw 24 contacting a hardened insert 25 in a boss 64 of member 13; the screw 24 having a lock-nut 67 and acting as adjustment means for brake clearance. For braking, a cable 75 rotates lever 19 about pivot 73 and lever 23 clockwise about pivot 59, the member 13 moving into engagement with disc 10; movement of member 13 is thereby arrested and lever action against pin 59 by lever 23 with its point of engagement with insert 25 as a fixed fulcrum urges member 12 to slide on rods 14, 15 into engagement with disc 10. Further force applied to lever 19 forces members 12 and 13 toward each other to powerfully grip the disc. On brake release a spring 78, connected between lever 19 and a fixed point, returns the levers to their normal brake released position; the spring may be omitted and the weight of lever 19 utilized for brake release. The disc 10 is formed with continuous, V- section grooves 32, 35, Fig. 4, encircling the disc axis, and increasing in depth from the outer to the inner.
