Abstract (en)
[origin: EP0341580A2] The invention relates to a process for purifying mercury-containing materials or material mixtures by distillation and/or to the recovery of mercury therefrom, which is characterised in that the charge material is, as a solid/liquid suspension or solution, injected into the distillation apparatus or atomised and/or sprayed therein, preferably by means of a rotary atomiser, and in that it is carried out at a pressure less than 1 bar, at a pressure reduced as compared with atmospheric pressure or in vacuo, and that the charge material is kept in motion. <IMAGE>
