Heavy Metal Recovery from Slags of Copper Production

2021-8-17  Slag cleaning with coke injection is also proven for zinc and lead slags. For the same reasons as in the copper industry, by-product treatment is a growing concern in the lead and zinc industry. After a 1 hour treatment, zinc content in the slag could be re-duced from 12.7 wt.% to less than 1 wt.% and Lead was reduced by the injection of coke
