Oxidation Sulfuric Acid Autoclave Leaching of Copper,
13-03-2019· Results are provided for sulfuric acid autoclave leaching of OAO SUMZ dust and dust obtained after recovery melting, containing alongside copper and zinc considerable amounts of lead and arsenic. The effect of temperature and acid concentration on autoclave leaching indices is studied.Does sulfuric acid react with copper? - Quora,Concentrated sulfuric acid is added to the copper in the flask. The mixture is heated. The heated air expands, and is pushed out of the flask. The copper reacts with the acid. One of the products is sulfur dioxide gas, which fills the flask. After the heat is removed, the gas in the flask cools, and contracts, drawing water into the flask.Sulfuric acid leaching for capturing value from copper,,01-04-2019· Sulfuric acid leaching of copper rich slag with the optimized parameters can provide a copper rich process solution with iron as the main impurity metal. The solution can provide an attractive feed for integration into the industrial primary copper production with acceptable low Ni, As and Pb levels (43.6 g/L Cu, 9.4 g/L Fe, 0.3 g/L Ni, 0.1 g/L As, 0.2 g/L Zn, 0.01 g/L Pb).
