ELECTROLYTIC PARTING OF DORE' METAL The dore' anodes are processed electrolytically to refine silver and separate gold. Four anodes are suspended from four separate buss bars in each Moebius cell. Each anode is encased in a polypropylene woven bag which collects gold mud as the anode dissolves.

Typical of these pyrometallurgical operations is "dore furnace" refining as practiced by the copper producers. Decopperized tankhouse slime is placed in a small reverberatory furnace to form a slag layer which is skimmed off. Antimony is volatilized and …

Once performed the retorting process, the product obtained is heated in a furnace in the presence of slag forming fluxes at temperatures over the melting point of all the components of the change, commonly between 1150 to 1450 o C. This operation is performed for around two hours to ensure complete separation of impurities from the precious metals.

Generally, the roasted slimes are charged to the Dore furnace for refining to metal for Moebius-cell parting. But in our treatment plant process, an electric furnace, two volatilizing furnace and a chloridizing furnace were used before the Dore furnace for the following reasons. 1) Minimizing precious metals content in the revert materials to

Reaction rates are about 4 times greater than using conventional cupel furnaces. The faster reaction rates improve productivity and reduce in-process precious metal tie-up. The furnace is also used to reduce litharge slag for bismuth recovery.
