Abstract

<PICT:0997402/C6-C7/1> In a process for the production of magnesium by reduction of dolomite with ferrosilicon or other metallic reducing agent, the reaction mixture passes downwardly through a reaction chamber while a current of inert scavenging gas (e.g. hydrogen or rare gas) is passed countercurrently through it. Simultaneously the colder parts of the apparatus may be scavenged with currents of the same or a different inert gas to prevent premature condensation. A particular form of apparatus described consists of a reaction chamber 1 in which charge material 14 is supported by grate 2, spent material being discharged through valve 4. Fresh charge is supplied by feeding device 11 and is heated by electric elements 9. The main stream of scavenging gas enters by pipe 5, passes upwards through the charge and carries magnesium vapour through conduit 7 to purification device 28, and thence condenser 15. Further inert gas is passed in through pipes 12. The condenser has two tubes 19, each being surrounded by superimposed casings 16, 17 and 18, and having within it a coolant pipe 20 fitted with baffles 23. Tubes 19 are connected to the necessary vacuum pumps by pipe 25. Vapour not condensing in chamber 15 is condensed in the condenser tube 19 in use until the latter is blocked. It is then sealed off, and the solid magnesium melted out by heaters 24. The pressure in chamber 15 is maintained at 25-90 mm. of mercury.
