Title: Process for treating a sulphide ore
IPC: C22B1/02
Filed: 1975-09-16
Abstract: 1500788 Treating sulphide ore NICHOLS ENG SA and J J M J A G DUPONT 16 Sept 1975 [26 Sept 1974] 38058/75 Heading C1A A sulphide ore comprising a principal sulphide and at least one auxiliary sulphide which is more volatile than the principal sulphide and/or is convertible by heating into such a more volatile sulphide is treated by heating the sulphide ore in an oxidizing atmosphere at a temperature below the oxidation temperature of the principal sulphide and secondly in a reducing or neutral atmosphere at a temperature between the volatilization points of the principal and auxiliary sulphide wherein a part of the labile sulphur and auxiliary sulphide are volatilized in the oxidizing atmosphere and the remainder being volatilized in the neutral atmosphere and then passed on to the oxidizing atmosphere, the whole of the labile sulphur and auxiliary sulphide being oxidized in the oxidizing atmosphere. The process is particularly directed to the treatment of pyrites which principally comprises FeS 2  which converts on heating into FeS and As 2 S 3  as an auxiliary sulphide. In the preferred embodiment, the sulphide ore is introduced into the top of an enclosure 1 through a charging device 18. The enclosure is provided with a rotary shaft 6 which carries scrapers 14, 15 which move the ore from the top of the enclosure to the bottom, falling consecutively from one floor 10 to another 11 within the enclosure. A flow of hot neutral or reducing gases is fed into the lower portion 21 to heat the ore to 400-1000 C. and cause volatilization of the labile sulphur and auxiliary sulphides. In the upper portion 22 the ore is heated in an oxidizing atmosphere at less than 425 C. by means of a flow of air fed in through an opening 26. The volatilized sulphur and sulphides from the lower portion are oxidized in the upper portion 22 and SO 2  passes out through vent 20. During its descent through the enclosure the ore undergoes complementary heating by the hot non-oxidizing gases. The treated ore issues from the enclosure through drain 19 and is preferably violently chilled in water. The thus chilled ore becomes porous and may be crushed for recovery of non-ferrous metals or may be fed to a sulphating roasting operation.

The rotor has a reflective face 5 perpendicular to its rotational axis 6, and is pivotally mounted on a ball 8 at the end of a fixed shaft 9 by half-cages 11, 12 and an elastic washer 13 held by a threaded ring 4. The ring 4 has teeth 16 meshing with a dog clutch 15 slidable along, but not rotatable on, a hollow shaft 17 rotatable on the shaft 9; the shaft 17 is riveted 21 to the innermost turn of a spiral spring 14. The spring 14 has its outer end attached to a casing 18 and is wound-up manually by a key 22 via a ratchet 23, winding-up also turns a flywheel 27 against a coil spring 28 as far as a stop (32) Figs. 3 to 5 (not shown) where it is held by a spring (29) against a notched wheel 26 carried by the flywheel 27. The stop (32) is movable in a groove (33) of a circuit board (34) but is held against such movement by a fuse wire (35). Application of electric current melts the fuse wire to release the flywheel 27 to tilt a lever (40) and release the ratchet 23 so that the spring 14 unwinds to turn the shaft 17, dog 15 and rotor 1, and via a spring 43 and clip 44, to pull the dog 15 clear of the teeth 16. Orientation of the rotor I about the ball 8 is effected by means of the disc 3 having bi-polar diametral magnetization, a solenoid 50 coaxial with the disc and two sensing coils 51, (52) spaced 90 degrees apart. Passage of the magnetized disc past the coils 51, (52) produces pulses according to the position and speed of the disc used to control (in respect of time, voltage and polarity) the supply of current pulses to the solenoid 50 for exerting a torque on the disc.

Abstract: 1493449 Coloured beverage mixes GENERAL FOODS CORP 23 Sept 1975 39035/75 Heading C6E [Also in Division A2] A process for preparing a coloured, dry food composition comprising crystalline particulate material selected from sugars, food acids and acid salts, e.g. a sucrose-based beverage mix, involves the steps of applying a colouring solute on to finely divided particles of tricalcium phosphate (TCP) and blending the so-coloured TCP and at least some of the crystalline particles of the final mix to cause portions of the coloured solute originally applied to the TCP to be transferred to and adhere on the surfaces of the crystalline particles. The TCP may be coloured by applying a colouring solution thereto and spray drying so that the TCP particles have a moisture content after drying of less than 0À50 wt. per cent. The TCP typically has a particle size such that at least 40% passes a No. 200VSS screen. Alternatively, the TCP may be coloured by blending finely divided tricalcium phosphate (TCP) and a minor amount of a water-colouring solute in a dry powdered condition, gradually metering a quantity of water on to the resulting blend to produce a superficially dry powder admixture wherein the water is uniformly distributed, and milling the moistened blend to evenly distribute the colouring solute throughout the TCP particles and coat them. An amount of water ranging from 10 to 25 wt. per cent based on the total charge of TCP particles, colouring solute and water, is added in this way and the TCP particles are subdivided by the milling to a particle size of less than 10 microns. The sucrose particles of the final mix may have been otherwise coloured prior to being blended with the coloured TCP. The proportion of coloured TCP in the final mix typically amounts to from 0À05 to 5À0 wt. per cent. The Examples relate to beverage mixes including conventional constituents in specified proportions.
