I. Technology

Due to the stable chemical properties of metal copper, it is poorly soluble in non-oxidative acid liquor. It is the most common soluble copper method to add oxidizing agent.

It is generally believed that copper dissolution in acid liquor containing air is a typical electrochemical reaction process, thus appropriate amount air can ensure oxidation potential of solution to facilitate the reaction.

II. Main technical and economic indicators

    Copper dissolution speed: ≥12kg/h·m3;                          Power consumption (ton copper): ≤400kw·h;

    Direct recovery rate: 99.9%;                                    Flue gas (H2SO4): ≤50mg/m3

III. Size and price
