1. A separation installation intended to receive a mixture containing at least a first family of components and a second family of components in order to separate the components belonging to the first family from the components belonging to the second family, said installation having an electrical thrashing chamber which comprises:
a receptacle, which is designed to receive the mixture and is provided with a screen,
a first electrode,
a second electrode placed facing the first electrode at a distance therefrom,
and a generator for applying an alternating voltage between the first electrode and the second electrode so as to generate, between said first and second electrodes, an agitating electrical field that is capable of alternately projecting all or some of the components of the mixture that is present in the receptacle towards or against the first electrode and then towards or against the second electrode, in order to generate mechanical impacts on said components that contribute to breaking down the mixture within the receptacle and in order to facilitate the passage of components belonging to the second family through the screen, while said screen ensures components belonging to the first family are retained in the receptacle.
