Definitions

  • the present invention is therefore based on the object of providing a process for separating a fraction containing non-ferrous metals into the respective non-ferrous metals, which on the one hand is said to be economically superior to the separation processes known in the prior art, but on the other hand also a satisfactory separation to ensure non-ferrous metals with high throughput.
  • a method should enable individual item sorting.
  • a method for separating a fraction containing non-ferrous metals into the respective non-ferrous metals comprises the following steps after optionally crushing the fraction containing non-ferrous metals and separating the ferromagnetic components from the fraction:
  • the non-ferrous metal fraction is treated with a solution of inorganic and / or organic reagents to produce a specific surface color of the individual non-ferrous metal fraction components depending on the respective non-ferrous metal.
  • the solution in step a) is an aqueous copper nitrate solution whose concentration is in the range from 1 to 5% by weight. based on the total weight of the solution.
  • the treatment time or contact time in step a) can be, for example, 1 to 30 minutes.

Abstract

L'invention concerne un procédé de séparation d'une fraction renfermant des métaux non ferreux, en métaux non ferreux respectifs, caractérisé en ce que la fraction renfermant les métaux non ferreux est traitée par au moins une solution d'un ou de plusieurs réactifs inorganiques et/ou organiques, de manière à produire une coloration superficielle spécifique des constituants individuels des fractions de métaux non ferreux, en fonction des métaux non ferreux respectifs, et en ce qu'ensuite les constituants individuels des fractions de métaux non ferreux sont triés suivant les colorations superficielles spécifiques respectives, et en particulier, collectés automatiquement.
