Leaching and recovery of zinc and copper from brass slag

The analysis of the residue (slag sample after leaching process) indicated that it contained only quartz (SiO 2) as the main constituent. 4. Conclusions. Leaching of brass slag to recover zinc and copper in sulfuric acid solutions was studied. It was found that the zinc extraction was fast and increased with sulfuric acid concentration.
