Describe parke's process of desilverisation of lead. – InterviewSolution

1.	Describe parke's process of desilverisation of lead.
Answer» Solution :Argentiferrous lead containing silver is extracted by Parke.s PROCESS BASED on the principle of distribution law. Molten lead and Molten zinc are immisible LIQUIDS. Molten zinc is lighter and forms upper layer. Silver is more soluble in Molten zinc than in Molten lead. The distribution RATIO of silver 300 to `500^(@)C` on cooling zinc layer solidifies extraction all silver is extracted. Zinc silver alloy is distilled in fire CLAY retort. Zinc distills over leaving behind silver.
