Abstract
The present invention has for its objects a process for extracting the chemical elements contained in diverse products (i.e. waste, ashes, used catalysts, etc. . . .) or in raw materials such as soils, sediments, lands, brownfields and ores and a device to implement the process. The process consists in forming volatile compounds with one or several elements to be extracted present in a first reactor using a gas being maintained outside of thermodynamic equilibrium as in non-thermal plasma (electric discharge under high or low pressure, corona discharge . . . ). These volatile compounds are then exhausted towards secondary reactors intended to selectively extract said volatile compounds by decomposition or by condensation to recover each elements and the gas which can be recycled.
