Alkaline leaching of zinc from electric arc furnace steel ...

2006-4-1  Indeed, in about 10 min of leaching, more than 50% of the recovered zinc was already dissolved. The additional extraction obtained after 2 h of leaching, achieved for NaOH concentrations of 2 and 6 M, is likely to be associated to the dissolution of some entrapped zinc or, alternatively, to the destruction of zinc ferrites. On the other hand, only 0.3% of the iron in the dust was dissolved,
