Abstract: 520,740. Decomposing zirconium ores. I. G. FARBENINDUSTRIE AKT.-GES. Oct. 29, 1938, No. 31359. Convention date, Oct. 30, 1937. Drawings to Specification. [Class 1 (iii)] Zirconium ores containing a substantial amount of zirconium oxide and zirconium silicate are chlorinated at 400-1,000‹C. to form and volatilise zirconium tetrachloride from a major part of the oxide content, and the ore residue then subjected to an alkaline decomposition treatment, preferably with lime, at 800- 1200‹C. to bring the remaining oxide and the silicate content into an acid-soluble form. Chlorination may be effected by passing the ore in countercurrent to phosgene through a revolving furnace at 500-600‹C. Sublimed tetrachloride may be decomposed with water to yield the oxychloride and evolve hydrochlorine acid, and the latter and the waste gases obtained in the chlorination step be used to acidify a suspension in water of the alkaline decomposition product. After separating silicic acid from the solution so obtained alkaline decomposition product may be added to alkalinity to precipitate zirconium hydroxide, which may then be dissolved in the hot acid oxychloride solution from the water-decomposition of the tetrachloride. The oxychloride may then be separated by crystallization.

The cold produced by a reversed hot-gas engine 1 is conveyed to a chamber 19 by a secondary evaporating-condensing system containing, at 20‹C., less than 1 gram molecule per cubic decimetre of an auxiliary medium the boiling point of which at a pressure of 20 atmospheres is less than 20‹C. Suitable media are methane, ethane, nitrogen. As shown in Fig. 1, the medium is condensed in chamber 14 on the cold end 8 of the engine and is pumped by pump 17 to the evaporator 18 in chamber 19, the vapour returning to chamber 14 by pipe 20. If the load decreases, excess liquid medium overflows a wall 15 into a chamber 22 where it is re-evaporated by heat conveyed from the cooling-water pipe 26 of the engine through a heat-conducting body 25, 24, 23. Alternatively, the excess medium may be re-evaporated by an electric heater or by the heat of ambient air. As shown in Fig. 2, a chamber 30 is connected to pipe 20 by pipes 31, 32 containing respectively a non-return valve 33 and a cock 34. At the start and during running cock 34 is open and medium is withdrawn from the chamber 30 to circulate in the system. At the end of operation, cock 34 is closed and excess pressure is avoided as the system warms up, by medium passing into chamber 30 through non-return valve 33. A device 35, 36, 37 detects the temperature or pressure of the medium and actuates means controlling the speed of motor 13 driving the engine 1 or the pressure of the working gas in the engine. The cold output of the engine may be changed by altering the relative phase of the piston and displacer or by altering the clearance space in the engine or. by stopping and starting of the engine. The level of excess medium condensate in a float chamber may control the cold output of the engine. Specification 695,857 is referred to.
