Process for the precipitation of arsenic and heavy metals from acidic process water |
| abstract |
Process for the precipitation of arsenic and heavy metals from acidic process water (12), comprising a precipitation process section (II) with a sulfide precipitation phase (C) where arsenic and at least one primary heavy metal, adding a sulfide precipitation reagent (16) to the process water (12), so that the arsenic precipitates as arsenic sulfide and the at least one primary heavy metal precipitates as metal sulfide. |
