Abstract
The Outotec’s Chemical Reaction and Equilibrium Software HSC Chemistry software was used to make balance calculations for multicomponent equilibrium compounds in a heterophase gas-liquid-solid system under oxidizing fusion of the decoppered anode slime with sulfur, selenium and tellurium dioxides entering the gas phase, while the compounds of lead, copper, antimony, iron, and aluminum are concentrated in silicate slag. The study findings are as follows: under optimal conditions for the oxidizing fusion of the mixture (100 kg) of the anode slime (O2 » 0,9 kg; SiO2 ³ 6 %; CaO ~ 3 %; t = 1200 °C), lead, antimony and arsenic almost completely pass into silicate slag, while copper and silver (over 91 %) pass into matte. Selenium is distributed between the gas phase (49,8 %), matte (24,1 %), and metal phase (26,1 %); while tellurium is distributed between the fumes (14,4 %), silicate slag (8,4 %), and matte (77,2 %).
