Recovery Of Zinc from Scrap Steel Using Zinc‐Bromine Battery Technology
Secondary production of steel is known to significantly decrease the CO2 emissions of steelmaking, but only 40 % of steel is produced through recycling, which is made difficult by contamination of scrap resources with nonferrous metals and nonmetal debris.

| description | Secondary production of steel is known to significantly decrease the CO2 emissions of steelmaking, but only 40 % of steel is produced through recycling, which is made difficult by contamination of scrap resources with nonferrous metals and nonmetal debris. These contaminants include zinc, towards which blast furnace and electric arc systems have a low tolerance (99.9 wt % zinc from steel surfaces. On recharging the cell, zinc was re‐electroplated onto a carbon foam electrode in an easily recoverable form and with high purity. The process was repeated over 30 cycles to demonstrate robustness. The work shows the importance of the cutoff voltage upon discharging: if less than 0.5 V, the cell co‐extracted iron into the electrolyte solution, affecting cell durability and zinc purity. A two‐stage process for recovering zinc from scrap steel is proposed, illustrating how ZBB technology could enable efficient and clean recovery of zinc from complex scrap steel resources in the steel industry.
Scrapper's delight: Zinc‐bromine battery (ZBB) technology could enable efficient and clean recovery of zinc from scrap steel and therefore help to increase steel recycling and secondary steel production rates and make the prospects for green steel production more realistic. A two‐stage process for recovering zinc from scrap steel using ZBBs is proposed. |
