Division 1.2.6 Waste
United Kingdom
| Technique | Applicability | |
|---|---|---|
| a | Recover metals from the dust and slime coming from the dust abatement system | Generally applicable |
| b | Reuse or sell the calcium compounds (e.g. gypsum) generated by the abatement of SO2 | Applicability may be restricted depending on the metal content and on the availability of a market |
| c | Regenerate or recycle the spent catalysts | Generally applicable |
| d | Recover metal from the waste water treatment slime | Applicability may be restricted depending on the metal content and on the availability of a market/process |
| e | Use weak acid in the leaching process or for gypsum production | Generally applicable |
| f | Recover the copper content from the rich slag in the slag furnace or slag flotation plant | |
| g | Use the final slag from furnaces as an abrasive or (road) construction material or for another viable application | Applicability may be restricted depending on the metal content and on the availability of a market |
| h | Use the furnace lining for recovery of metals or reuse as refractory material | |
| i | Use the slag from the slag flotation as an abrasive or construction material or for another viable application | |
| j | Use the skimming from the melting furnaces to recover the metal content | Generally applicable |
| k | Use the spent electrolyte bleed to recover copper and nickel. Reuse the remaining acid to make up the new electrolyte or to produce gypsum | |
| l | Use the spent anode as a cooling material in pyrometallurgical copper refining or remelting | |
| m | Use anode slime to recover precious metals | |
| n | Use the gypsum from the waste water treatment plant in the pyrometallurgical process or for sale | Applicability may be restricted depending on the quality of the generated gypsum |
| o | Recover metals from sludge | Generally applicable |
| p | Reuse the depleted electrolyte from the hydrometallurgical copper process as a leaching agent | Applicability may be restricted depending on the metal content and on the availability of a market/process |
| q | Recycle copper scales from rolling in a copper smelter | Generally applicable |
| r | Recover metals from the spent acid pickling solution and reuse the cleaned acid solution |
