Lead-Zinc Mine
Lead is one of the earliest metals smelted by humans from lead-zinc ores. It is one of the softest heavy metals and one of the densest. It is blue-grey, hardness 1.5, specific gravity 11.34, melting point 327.4°C, boiling point 1750°C, with good ductility, easily alloyed with other metals (such as zinc, tin, antimony, arsenic, etc.).
Lead is one of the earliest metals extracted by humans from lead-zinc ores. It is one of the softest heavy metals and also one of the heavier metals, with a blue gray color, hardness of 1.5, specific gravity of 11.34, melting point of 327.4 ℃, boiling point of 1750 ℃, good ductility, and easy to alloy with other metals such as zinc, tin, antimony, arsenic, etc. Lead zinc ore is an important raw material for extracting associated metals such as lead, zinc, silver, gold, copper, tin, antimony, etc. It is widely used in fields such as batteries, alloys, galvanizing, and chemical engineering.
