Lead and Zinc - Energy

2013-11-8  Zinc metal is never found pure in nature. Zinc minerals are generally associated with other metal minerals, the most common associations in ores being zinc-lead, lead-zinc, zinc-copper, copper-zinc, zinc-silver, or zinc only. Zinc also occurs in combination with sulfur in a mineral called zinc blende or sphalerite (ZnS). The primary source of ...

2021-11-9  Palden et al. [] studied the solvometallurgical method-selective leaching of lead and zinc from iron-rich jarosite in the zinc industry.Testing the various leaching agents showed that the presence of chloride anions is crucial for lead leaching. Ionic liquids, such as Aliquat 336 ((A336) (Cl)) and Cyphos IL 101 ((C101) (Cl)), were found to leach more lead and zinc after equilibration with HCl ...
