Patent GB-412629-A (GB)
Title: Improvements in or relating to the extraction of tin from ores or the like
IPC: C22B1/08
Filed: 1932-12-24
Abstract: <PICT:0412629/III/1> In the recovery of tin from ores, especially ores containing oxidized iron, by the use of solid chloridizing agents with volatilization of tin as stannous chloride, the ore is heated and partially reduced, as by heating with carbonaceous material or in a reducing atmosphere, before the chloridizing agent is added. Alternatively, or in addition, the process is so conducted that gases produced are prevented from escaping without coming into contact with a heated body of partially reduced ore.  In carrying out the process, the ore admixed with carbonaceous material may be fed from a shoot 8 into the first of two rotary cylinders 2, 3, heated as by oil burners 9 and interconnected by a stationary section 5.  The chloridizing agent, which may be calcium or ferrous chloride in treating basic ores, is fed from a hopper 11 on to the preheated and partially reduced ore, and chloridization is effected in the cylinder 3.  Stannous chloride vapours escape at 13 and the ore residue is discharged at 14.  Loss of chlorine, for instance as ferric chloride, is minimized by the preliminary reduction step, and/or by the passage of the volatile products of the chloridization reaction through or over the partially chloridized ore.  According to the second Provisional Specification, when acid ores are treated, the chloridizing agent may be sodium chloride.  Specifications 276,743, [Class 1 (i)], 403,122, and 403,123 are referred to.

Abstract: 1,114,306. Refrigerating. SULZER BROS. Ltd. 11 Aug., 1965 [5 July, 1965], No. 34356/65. Heading F4H. In a refrigeration system for supplying cold liquid refrigerant for use as the moderator in a nuclear reactor high-pressure gas from a compressor 1 is cooled in heat-exchangers 3 and 4, partially condensed in a heat-exchanger 5, condensed and super-cooled in a heat-exchanger 6 by evaporating liquid refrigerant, expanded to an intermediate pressure in throttle 7 and passed through a moderator vessel 11 while still in liquid form. The returning liquid refrigerant may, as shown, be divided into two streams one of which is expanded to a low pressure in throttle 8 and used to supercool exchanger 6 and the other of which is evaporated and superheated in exchangers 5, 4 while cooling the highpressure refrigerant, then expanded in one or more turbines 9 to the same pressure as that produced by throttle 8. The evaporated refrigerant from heat-exchanger 6 passes through heat-exchanger 5 and is combined with the gas from the turbine discharge, the combined stream being returned to the compressor 1 via heatexchangers 4, 3 and pressure vessel 14. Throttle 8 is controlled by means 13 to maintain a constant liquid level in exchanger 6 and throttle 7 is controlled by means 12 to maintain the liquid supplied to the moderator at constant pressure. Approximately 92% of the liquid refrigerant from moderator 11 is supplied to turbine 9 and 8% to throttle 8. In a modification (not shown) all of the returning refrigerant is passed to turbine 9 and the liquid refrigerant for heat-exchanger 6 is derived from the higher pressure liquid stream upstream or downstream of exchanger 6 and throttled to said low pressure. The refrigerant may be hydrogen or hydrogen deuteride. Illustrative flow rates, temperatures and pressures are given.
