INERT ANODE ALUMINUM ELECTROLYTIC CELL WITH VERTICAL STRUCTURE
The present disclosure relates to a field of aluminum smelting, and in particular to an inert anode aluminum electrolytic cell with a vertical structure, which includes: an electrolytic cell shell (1), a heating device (5) and a graphite base (13). The electrolytic cell shell (1) is provided with three insulating layers therein. The heating device (5) is disposed in the groove on the first insulating layer (4) The graphite base (13) is disposed at a bottom of an inner cavity of the electrolytic cell shell (1). A bottom of the graphite base (13) is opened with a mounting slot. The cathode is vertically mounted in the installation slot. The anode (17) is arranged in a staggered manner with the cathodes (16) and is suspended above the electrolytic cell shell (1) by connecting to a guide rod (11). A current of the anode (17) passes through the guide rod (11) and enters an interior of the electrolytic cell shell (1) from a top of the electrolytic cell, and the cathode (16) current is led out of the electrolytic cell shell through a metal electric rod (12).

RECOVERY OF GOLD AND/OR SILVER FROM SCRAP
Gold and silver are recovered selectively such that gold and silver are separated from non-silver and non-gold material within the scrap. Gold and silver are recovered from scrap material using mixtures of acids, in some instances. The mixture comprises nitric acid and at least one supplemental acid, such as sulfuric acid or phosphoric acid. The amount of nitric acid within the mixture are relatively small compared to the amount of sulfuric acid or phosphoric acid within the mixture. The recovery of gold and silver using the acid mixtures are enhanced by transporting an electric current between an electrode and the gold and silver of the scrap material. Acid mixtures are used to recover silver from particular types of scrap materials, such as scrap material comprising silver metal and cadmium oxide and scrap material comprising silver metal and tungsten metal.
