摘要： Phosphorus furnace slag and ferrophosphorus are separated from one another. To this end, a mixture of phosphorus furnace slag and ferrophosphorus, which is tapped off periodically from a phosphorus furnace, is introduced into a separating zone fitted with a bottom outlet and an overflow, through which the phosphorus furnace slag floating on the ferrophosphorus is delivered to a solidification zone. The separating zone has the dimensions necessary to receive the quantity of ferrophosphorus tapped off, which is allowed to remain therein for a period between 0.25 and 2 hours, so as to complete the separation of the phosphorus furnace slag by allowing it to solidify above the liquid ferrophosphorus. Liquid ferrophosphorus is finally discharged through the bottom outlet in the separating zone and delivered to a solidification zone.

摘要： The invention relates to a process for making red phosphorus by subjecting molten yellow phosphorus to a thermal conversion reaction in a closed reaction zone. To this end, a hollow shaft-provided and closed ball mill is preheated to a reaction temperature within the range 280.degree. to 590.degree. C. Yellow phosphorus is continuously introduced into the ball mill through the hollow shaft in quantities per unit time which permit the reaction temperature prevailing inside the ball mill to be maintained without supply of heat from the outside. More particularly, decreasing quantities of yellow phosphorus are introduced per unit time at increasing temperature and increasing quantities of yellow phosphorus are introduced per unit time at decreasing temperature within the limits specified. Red phosphorus is allowed to cool inside the ball mill, water is poured over it and the whole is subjected to wet-grinding. An aqueous suspension of red phosphorus is finally removed from the ball mill.

摘要： The invention relates to an apparatus for the production of phosphoric acid by subjecting yellow phosphorus to combustion inside a combustion tower, the apparatus comprising a cone-shaped shell with a flat bottom of acidproof material forming the combustion tower, the cone ratio of the shell being 1:10 to 1:12. An upwardly-directed off-gas outlet is secured to the lower portion of the shell and a plurality of downwardly directed spray nozzles is arranged so as to open through the middle portion of the shell into the interior of the combustion tower. An acid-receiving cup with an overflow weir is positioned near the upper end of the shell, the acid-receiving cup surrounding the combustion tower concentrically, being gas-tightly connected to, and supporting, a self-supporting cone-shaped tower cover having a passageway passed centrally through it. The overflow weir is formed of a tubular-annular structure disposed completely horizontally inside the acid-receiving cup. The tower cover forms, with respect to the horizontal, an angle .alpha. of at least 19.degree.. A water-cooled air inlet and a tubular holding means terminating in a phosphorus spray nozzle are hooked concentrically with respect to one another in, and are passed through the passageway in the cover.
