Abstract: Provided is a recovery method for valuable metals in copper anode slime. By using the recovery method of the disclosure, selenium, copper, tellurium, arsenic, lead, bismuth, and precious metals gold and silver in the copper anode slime are recovered. The method adopts two-step vacuum carbothermal reduction to replace reduction smelting of anode slime and stepwise blowing of noble lead in the traditional pyrometallurgy, and avoids the emission of arsenic-containing soot in the traditional process. The recovered gold-rich residue contains almost no base metals such as lead, bismuth, antimony, and arsenic. After subjecting the gold-rich residue to leaching gold by chlorination and reduction, a gold powder could be obtained therefrom with a lower content of base metals than traditional processes. Therefore, the method greatly reduces the amount of produced slag, shortens the production cycle, and reduces the loss of precious metals in the slag.

Abstract: Provides is a method for denitration of carbothermally reduced iron-containing nonferrous metal smelting slag mixed with advanced oxidizer. In the method, the iron-containing smelting slag is subjected to carbothermal reduction, such that metals or metal oxides in the smelting slag are reduced and transformed into active catalysts which could activate hydrogen peroxide to generate free radicals. Hydrogen peroxide is catalytically decomposed, generating ·OH free radicals, and ·OH free radicals generated further oxidize NOx. The reactions are performed at ambient temperature
