Decomposition of hard, sintered carbides

Restoration of hard, sintered carbides to the condition they were in prior to sintering, e.g. the tips of cutting tools, wearing plates, etc. which normally employ tungsten carbide with cobalt, by immersing the carbide body in a relatively weak phosphoric acid at slightly above room temp. to release the cobalt. The particles are then reobtained in almost their original size and are mechanically separated by filtration, etc.

An improved process for working up mixed shavings of white metal and red metal

... 270,740. Schwarz, A., (Assignee of Internationale Metall Akt.-Ges.). May 5, 1926, [Convention date]. Granulating.-Mixed turnings, shavings, &c., of white and red metals are treated to obtain the white and red metals separately by heating the mixture to such a temperature that the white metals but not the red metals are melted. The mixture is then subjected during slow cooling to disintegration, for example by scouring, the hard particles of red metal being utilised as scouring agents. The white metals are thereby caused to assume a finer grain than the particles of red metal and the mixture can thereafter be separated by sifting. A small proportion of graphite, charcoal, fluorspar, oil, tar, or other material may be added to the mixture before treatment. In a modification, the mixture is heated as above, but the greater part of the molten white metal is withdrawn before applying the disintegrating step, the addition of the graphite, &c., being essential in this case.

Recycling of copying cylinders or copying drums

In order to recycle copying cylinders or copying drums, any coatings present, which essentially consist of toxic selenium- and arsenic-containing compounds or alloys thereof, must be removed from the substrata. For detaching these coatings from the copying cylinders or copying drums, these are blasted with a granulated product consisting of plastic balls. The coating materials which are then present in the granulated product are separated from the latter in a flotation bath which consists of a salt solution with added wetting agents. The coating material is separated from the salt solution by filtration, dumped or worked up. The granulated product and the salt solution are recycled into the process. After the coating has been removed, the copying cylinders are either polished, newly coated and re-used or recycled as waste metal. ...

Process of treating amalgams of metals which are difficultly soluble in mercury

An amalgam containing less than 10 per cent by weight of a metal difficulty soluble in mercury is heated to a temperature above 360 DEG C. at a pressure equal to or higher than the vapour pressure of mercury at that temperature to condition the amalgam for separation of mercury therefrom in the liquid phase. Separation of further mercury from the residual amalgam can be effected by oxidizing the metal in the residual amalgam to form an oxide covered amalgam powder and mercury substantially free from the difficulty soluble metal. Oxidation can be facilitated by adding to the amalgam, at any time before separation of mercury, a metal having a higher affinity for oxygen than the said difficulty soluble metal. The added metal may e.g. be aluminium added in amount of 10-4 to 10-2 per cent by weight of the mercury in the amalgam, or manganese added in amount of 10-3 to 10-1 per cent by weight of the mercury. The difficulty soluble metal may be obtained from the final enriched amalgam by distillation ...
