Recent work on Electric Arc Furnace Dusts (EAFD) has proven extremely encouraging with zinc recoveries of >80% producing solutions of >40g/L zinc with low impurities. The market for zinc oxide is large and this can be produced directly from the leach solution.
All the best (no I can't........ there's two of you ffs.......!)
Metallurgical slag and dust (MSD) from lead and zinc smelting, steel dust and galvanized steel scrap are important secondary sources of zinc and other valuable metals. This paper describes the production feasibility and rationality of a cleaner zinc recovery process using MSD and a hydrometallurgical method. It was found that the addition of CH3COONH4 to a NH3–H2O system promotes zinc extraction, and 83.76% of zinc could be dissolved and recovered from the MSD under the following conditions: total ammonia concentration of 5 mol l
