Apparatus is suitable mainly as part of the technologic line for purification of waste water containing dissolved metal forms or for the use in the hydrometalurgy. It consists of the fluid reactor (1) filled with a charge (11) of metal particles with a lower electrochemical potential than that of the separated metal, further of the separator (2) of the particular form of separated metal and the metering device of the particular form of separated metal. The apparatus parts are interconnected with a circulating pipeline (4). The solution containing dissolved metal forms is brought into the fluid reactor (1). The electrochemical cementation process with fluidized metal particles is realized, in which the metal with the higher electrochemical potential is reduced by its own electrochemical reaction and it is separated in solid form. The process of electrochemical cementation is autocatalysed by the controlled metering of the particular form of separated metal. |
