Division BAT 53
United Kingdom
In order to prevent the generation of waste water from primary and secondary copper production, BAT is to use one or a combination of the techniques given below.
| Technique | |
|---|---|
| a | Use the steam condensate for heating the electrolysis cells, to wash the copper cathodes or send it back to steam boiler |
| b | Reuse the water collected from the cooling area, flotation process and hydro transportation of final slag in the slag concentration process |
| c | Recycle the pickling solutions and the rinse water |
| d | Treat the residues (crude) from the solvent extraction step in hydrometallurgical copper production to recover the organic solution content |
| e | Centrifuge the slurry from cleaning and settlers from the solvent extraction step in hydrometallurgical copper production |
| f | Reuse the electrolysis bleed after the metal removal stage in the electrowinning and/or the leaching process |
