Metals are recovered from Ni base alloy scrap containing Ni, Co and Cr with optional additions of one or more of Mo, Fe, Al, Ti, Mn, Si, W, C, Cu and Nb by:- (a) Dissolving metal values therefrom with aqueous HCl with the optional incorporation of chlorine gas; (b) Adding MgO to the solution until it has a pH of 2-4, whereby Cr and any Fe are precipitated, and separating the precipitate from the liquid phase; (c) Effecting liquid/liquid extraction under acidic chloride conditions using an organic phase so that any acidic cobalt chloride complex formed in the aqueous phase passes into the organic phase; (Stages (b) and (c) can be used in the above order or stage (c) may precede stage (b).) (d) Adding MgO to the resulting aqueous phase to give a pH of 7À5-8 and precipitate nickel which is separated from the liquid phase, which latter is then heated to produce MgO and HCl; and (e) Recycling the MgO to at least one of stages (b) and (d) and the HCl to stage (a). When stage (c) precedes stage (b) the latter may combine with stage (d) and high pressure hydrogen used to selectively reduce Ni from the mixed Ni, Cr  Fe hydroxides. Any Mo values in the solution formed in stage (a) are removed, prior to the first of stages (b) or (c), by contact of the solution with activated carbon, preferably after contacting with Cl 2  gas to increase the valency state thereof and eluted from the column as Na or NH 4  molybdate which may be precipitated as Ca molybdate using a Ca salt. Alternatively the Mo may be removed by counter-current extraction with tri-butyl phosphate. Metals may be recovered from the various solutions or precipitates by suitable methods such as hydrogen reduction.

Abstract: 1,012,419. Electric selective signalling. M. DENTZER. Dec. 30, 1963 [Dec. 29, 1962; Oct. 2, 1963], No. 51121/63. Heading G4H. [Also in Division G1] A magnitude-measuring arrangement comprises means controlled by the magnitude to drive across a reading head 38 a signal carrier 37, the signals carried by which are spaced by amounts corresponding to units of the magnitude to be measured, counting means 45 being controlled by the reading head 38. In Fig. 5, a condenser 29 responds to liquid level in a container R1 to detune a frequency discriminator 19 from the frequency of a quartz crystal oscillator 18, this resulting in a D.C. voltage at v which is amplified at 31 and then used to drive a motor 24. Motor 24 drives magnetic tape 37 (or a disc) bearing pulse signals past a reading head 38 and also adjusts a condenser to retune the discriminator 19. Pulses picked up by reading head 38 are counted in a thyratron ring counter 45 in a direction depending, through the agency of a biased relay 39, on the polarity of the amplified D.C. fed to the motor 24. The motor direction also depends on the polarity. The signals on the tape 37 can be so spaced that the counter 45 indicates the volume of liquid in the container R1 rather than its depth: the spacing can be done experimentally using the required container R1. A switch 46 allows any one of three similar containers to be coupled to the counter 45. The taking of a reading is preceded by the zero-positioning of tape 37: until current has built up sufficiently through a delaying resistance 23 to operate a relay 22, this relay keeps a condenser 21 in circuit in place of the condenser 29, condenser 21 having a capacity equal to that of condenser 29 when there is no liquid in container R1. The counter 45 is also reset to zero. Fig. 8 (not shown) shows diagrammatically a modification in which weight of goods controls a condenser, and the counter besides displaying the weight, feeds the latter to a multiplying device to calculate the price, the price per unit weight being fed to the multiplying device from a keyboard. The price is displayed and also printed on a check ticket. The counter cannot produce output signals unless the price per unit weight has already been set up on the keyboard.
