释义
Parkes process

Chemical Engineering
  • A metallurgical process for the removal of silver from lead using zinc in liquid–liquid extraction. Zinc is immiscible with lead and its addition to lead containing silver as a contaminant results in silver dissolving in the zinc. The zinc-silver solution is then separated and the zinc removed from the silver by distillation. The process was patented in 1850 by British metallurgist Alexander Parkes (1813–90).
