Zinc
Zinc is found in several ores, the principal ones being zinc blende (zinc sulfide) and calamine (zinc silicate). The principal mining areas are in China, Australia and Peru. Commercially, zinc is obtained from its ores by concentrating and roasting the ore, then reducing it to zinc by heating with carbon or by electrolysis.

Silver Mineral | Physical
Lead melts at 327 °C, lead oxide at 888 °C and silver melts at 960 °C. To separate the silver, the alloy is melted again at the high temperature of 960 °C to 1000 °C in an oxidizing environment. The lead oxidises to lead monoxide, then known as litharge, which captures the oxygen from the other metals present.
