Abstract: 687,758. Electrolytic production of aluminium. SOC. ANON. POUR L'INDUSTRIE DE L'ALUMINIUM. Feb. 27, 1951, No. 4767/51. Class 41. In a process for the electrolytic production of aluminium by electrolysing a melt comprising aluminium chloride and other metal chlorides at a temperature above the melting temperature of aluminium using insoluble and non- consumable anodes and collecting the aluminium at the bottom of the electrolytic cell, the chloride metal comprises at least one mole alkali-metal chlorides to each mole aluminium chloride and contains at least two alkalimetal chlorides and at least one chloride of a metal of the alkaline-earth group (including magnesium) the melt being circulated through the cell and being continuously withdrawn from the cell and returned thereto after being enriched with aluminium chloride outside the cell. Potassium chloride may be one of the alkali-metal chlorides, the molecular ratio of aluminium chloride to potassium chloride being between 1 to 1 and 1 to 12. The chloride melt may contain magnesium chloride and lithium chloride in a molecular ratio to each other of between 1 to 1.5 and 1 to 4. Sodium chloride or lithium fluoride or both may be added to the electrolyte to improve its conductivity. Electrolysis may take place in apparatus as shown, in which a vessel 1 is divided into single cells by partitions 12, each comprising a ceramic frame carrying a graphite plate 15 which acts as a bipolar electrode. Each frame has an inclined channel-like portion 16 which collects the aluminium on the cathode side of the plate 15 and conducts it to a receiver 17. Each receiver may be tilted about a pivot 18, by means including a supporting stud 20 fixed to a rod 30 which can be raised or lowered on rotation of a shaft 21. The molten aluminium is thus run into a sump 24 from which it is removed by means of a suction pipe 8. The vessel 1 is provided with apertures 4 for electric conductors 5 and with inlet and outlet apertures for circulation of electrolyte. Apertures 25 are provided alternately at the top and bottom of guide ribs 13 to cause the electrolyte to flow in a zig-zag course through the cells. Carbonaceous packing material 27 fills the space around the conductors 5.

Apparatus for counter-current treatment of particulate solids with a liquid comprises a vertical flow treatment zone in which are spaced flow obstructions designed for the downward passage therethrough of solids, means for introducing the solids to the vertical zone near the top, means for introducing treatment liquid to the zone near the bottom for counter-current upward movement, means for discharging liquid from near the top and solids, with some liquid, from near the bottom and means for pulsating the contents of the zone to compel the solid particles to pass through openings in the obstructions at each downward pulse, effecting a net downward transfer of the solids uniformly distributed across the treatment zone as well as uniform upward flow distribution of pulsating liquid. The treatment zone 17 in a vertical column 10 contains axially adjacent compartments defined between spaced perforated trays 18. The feed material to be treated is introduced at 11 and sinks down the column, meeting treatment liquid introduced at 12 and caused to flow upwards by a pump 13 till it overflows at 14. The treated product is extracted by a pump 16. The strokes of the pumps 13, 16 are synchronized to cause pulsation of the material in the column. In a modification, Fig. 2, a plurality of sieve tray units 21 are used, each comprising a central tray 22 with few openings 23 and, spaced above and below it, trays 24 with many openings 25. The feed material enters at 29 and the treatment liquid enters at 27, 33. A device 26 causes the pulsation. The treated product leaves at 28. To minimize turbulence at the feed, the upper end of the column is enlarged and is spanned by sieve trays 32. The feed conduit may enter at the side, in which case the sieve trays 32 can extend right across. Pulsation may also be achieved by relative movement between the sieve trays and the columns.

Title: Improvements in precipitating zinc sulphide
IPC: C09C1/06
Filed: 1938-02-19
Abstract: <PICT:0495277/III/1> In a method of precipitating zinc sulphide wherein a batch of zinc salt solution is reacted with hydrogen sulphide gas by repeatedly vigorously spraying the solution through the gas, each batch of the solution is introduced into the precipitation chamber before the spraying operation is started in such a manner that reaction with any gas in the chamber is avoided as far as possible, as by smoothly introducing the solution into the bottom of the chamber which may be filled with an atmosphere of concentrated hydrogen sulphide gas.  Before introduction of a new batch of solution the precipitation chamber is thoroughly washed to remove residual precipitate or acid from a previous operation.  The process may be carried out in a chamber 1 provided with a circulating pump 5, Venturi tube eductor 7 and pipes 16, 19 for supplying hydrogen sulphide gas respectively from the chamber and a supply source.  A pipe 20 is provided to maintain the partial pressure of gas in the chamber 1 constant.  Zinc sulphate solution is introduced initially through a pipe 2.  The settling rate of the crude precipitate may be controlled by regulating the velocity of circulation through the pump 5, the partial pressure of hydrogen sulphide, the pH value or temperature of the circulating liquid, or the zinc content of the initial solution.  Specifications 435,287 and 439,311 are referred to.
