Method for separating arsenic and heavy metals in an acidic washing solution |
| abstract |
A method for separating arsenic and heavy metals in an acidic washing solution which contains both arsenic and heavy metal, more particularly in a washing solution (12) which is formed in copper smelting and contains sulphuric acid, comprises a separation process section (II), in which arsenic and at least one primary heavy metal are separated from one another. The separation process section (II) comprises a processing step (C), in which hydrogen peroxide H2O2 is added to the washing solution (12), and the separation process section (II) comprises a precipitation stage (D), in which the washing solution is admixed with a sulphide precipitation reagent, causing the at least one primary heavy metal to precipitate in the form of a metal sulphide. The processing step (C) in this system is carried out before the precipitation stage (D). |
