lead metal ore gold miune

Lead

Galena, a principal ore of lead, Zinc, which is immiscible in lead, dissolves the silver and gold. The zinc solution can be separated from the lead, and the silver and gold retrieved. Lead metal has several useful mechanical properties, including high density, low melting point, ductility, and relative inertness.
