Patent GB-375795-A (GB)
Title: Improvements in the chlorination of materials containing iron sulphide
IPC: C01B17/06
Filed: 1931-02-25
Abstract: In the recovery of sulphur from iron sulphide containing materials, the materials are subjected to the action of a chlorinating agent to produce ferrous and other heavy metal chlorides, such as those of nickel and copper, and volatilized sulphur which is condensed, the residue of chlorides being treated with chlorine to form and volatilize ferric chloride which is hydrolyzed with steam to produce hydrogen chloride from which, by oxidation with air, chlorine is obtained and returned to the process.  The powdered material is fed into one end of a rotary reaction chamber and sulphur chloride is introduced into the other.  A temperature of about 450 DEG  C. is maintained at the charging end and one of 300-350 DEG  C. at the discharging end. Formation of ferric chloride is effected by treatment of the hot residue in a rotary reaction chamber, chlorine being passed in countercurrent; temperatures above 315 DEG  C., preferably 350 DEG  C., are employed.  The residue contains nickel and copper chlorides which may be extracted therefrom.  The condensed ferric chloride is hydrolyzed by superheated steam at 300-400  DEG C., preferably 350 DEG  C., to produce ferric oxide and hydrogen chloride which is dried by sulphuric acid and is treated, in the presence of a catalyst, e.g. nickel or copper sulphate or chloride carried by pumice &c., with air heated above 420 DEG  C., preferably to 530 DEG  C., to which temperature the hydrogen chloride may be preheated.  The salts constituting the catalyst may be applied directly to the carrier or be formed by the action of the hydrogen chloride on an oxide, e.g. copper oxide, distributed on the carrier. The reaction is exothermic and is controlled to keep the temperature between 370 DEG  and 400 DEG  C., but 470 DEG  C. may be used.  As the reaction does not proceed to completion, the gases may be dried and passed through further reaction chambers; the chlorine is finally separated from hydrogen chloride by washing with water and drying. Sulphur chloride may then be regenerated by passing the chlorine and inert gases through molten sulphur kept above the boiling point of sulphur chloride, e.g. at 150 DEG  C.  The sulphuric acid used for drying the hydrogen chloride is combined with the wash water from the chlorine and is concentrated, that part of the steam containing hydrogen chloride being used to treat the ferric chloride. Specifications 374,069, 347,070, and 375,370 are referred to.

The workpiece 1 which may be a cylindrical cutter having straight or helical teeth is mounted between a headstock spindle 2a and a tailstock 3. The grinding wheel 5 is mounted on a shaft 21 which is driven by an oil motor 25 and supported in the grinding head 24. The latter is movable radially of the grinding wheel on guide rods 22, 23 extending from a mounting plate 26 adjustable about an axis 27 on the carriage 4 by an electric motor and worm drive to position the grinding wheel according to the helix of the cutter. The carriage is movable axially of the workpiece along a guide cylinder 7 by a cylinder 8 secured to the carriage and movable over a fixed piston 11. Rotation of the carriage about the guide cylinder is prevented by a rail 12 secured to the carriage and extending between roller 13 on the machine bed. The rail is formed with a rack engaging a gear 15 which, through a gear 16, shaft 7 and further gearing rotates the workpiece spindle 2a in accordance to the movement of the carriage. The radial advance of the grinding head is effected by the piston 29a which is secured to the head and is slidable in the cylinder 30 mounted in the carriage and connected to the plate 26, the cylinder acting as a pivot for the plate. The nut 34 is disposed within the hollow rod 29b of the piston and prevented from rotating relative thereto by a tongue-and-groove arrangement 35, 36. The end positions of the piston are determined by engagement with the nut which is axially adjustable by rotation of the spindle 33 engaging the nut. Rotation of the spindle is effected by a worm wheel 33a driven by a rotating field magnet 37. Stop-pins 38, 39, 40, 41 prevent jamming of the nut against the ends of the piston. In operation, the stop nut 34 may be so adjusted that the grinding wheel enters the workpiece to the full depth of the cut and at the end of the stroke of the carriage is withdrawn while the carriage returns to its initial position. If several passes are required by the grinding wheel, the advance of the wheel is controlled by a detent disc 42 which permits rotation of the spindle 33 by the magnet 37 each time a pawl is lifted until the grinding wheel has reached the required depth, the piston being engaged with the nut throughout the operation.
