The present invention relates, on one hand, to a metal cementing apparatus (1) formed by a vessel (2) with a liquid phase formed by a solution (3) containing noble metal, and a solid phase formed by a cementing metal or a less noble metal in contact with the solution (3), where one of said phases moves at a high speed with respect to the other one, and the difference in speeds allows the cementation of the noble metal on the solid phase, and the simultaneous detachment and separation thereof, and comprises means for generating the movement of at least the phase with the high speed and removing means for removing the precipitated noble metal. The invention describes, on the other hand, a continuous cementation method consisting of passing a continuous flow of solution in a vessel (2); reacting the solid phase with the liquid phase, where one of said phases moves at a high speed with respect to the other one, causing the fixing of the noble metal and the simultaneous detachment thereof; removing the precipitated noble metal.
A metal cementing apparatus wherein said metal cementing apparatus is formed by a vessel or a tank having therein a liquid phase formed by a solution containing a noble metal, and a solid phase formed by a cementing metal or a metal less noble than the one mentioned above, placed in contact with the solution characterized in that one of said phases moves at a high speed in relation to the other phase, with the difference in speeds being such that it allows the cementation of the noble metal on the solid phase and the simultaneous detachment and separation thereof, and comprises means for generating the movement of at least the phase having the high speed and removing means for removing the precipitated noble metal from the bottom of the tank to the outside thereof.
