Abstract: METERING DEVICE The disclosure relates to a device for metering liquid yellow phosphorus into a rotating ball mill for the production of red phosphorus therein. The device is more specifically comprised of a stationary outer tubular structure surrounding an inner tubular structure rotatably mounted therein. A valve having a valve rod associated with it is installed within the inner tubular structure near its end close to the ball mill. A plug provided with a central bore receiving the valve rod is installed within the inner tubular structure near its end remote from the ball mill. A bellows surrounds a portion of the valve rod inside the inner tubular structure, the bellows being tightly connected to the plug and valve rod.

Abstract: The invention relates to a process for separating seminoble and/or noble metals from an aqueous solution having compounds of these metals dissolved therein by subjecting the solution to reaction with red phosphorus. More particularly, the solution is conveyed through a zone containing a layer of granular red phosphorus particles with a size of 0.01 to 10 mm, which may be used in admixture with active carbon.

Abstract: 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 to 590.degree.C. Yellow phosphorus is continuously introduced into the ball mill through the hollow shaft in quantities per unit time through the hollow shaft 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.
