Zinc and lead extraction from Çinkur leach DeepDyve

NaCl leaching for lead recovery After water leaching, the secondary zinc plant residue (SZPR) was subjected to NaCl leaching to investigate the recovery of lead. The effects of NaCl concentration (50–300 g/l), SZPR pulp density (5–300 g/L), leaching temperature (25–80 8C), and time (5– 120 min) were investigated. All experiments were performed in duplicate and the mean values were
