How can zinc be separated from lead in the condenser?
In the blast furnace a mixed lead/zinc sinter is added and the lead bullion is tapped conventionally from the bottom of the furnace while metallic zinc vapour is distilled off and captured/condensed by a spray of molten lead droplets. A solution of zinc and lead leaving the condenser, when cooled this cool zinc can be floated off, while the lead is recirculated to the collector. Zinc being less dense can be continuously removed from the top layers.
Why does silver and zinc react?
Zinc is more reactive than Lead nitrate (See Displacement Series). Therefore, Zinc will displace lead in lead nitrate: Zn + Pb(NO3)2 -> Zn(NO3)2 + Pb
Which metal was often confused with lead and tin?
Zinc was often confused with lead and tin due to their similar appearances. However, zinc has a higher melting point than lead and tin, and it does not oxidize easily like lead and tin.
How many areas produce the minerals lead and zinc?
Lead and zinc are typically found together, so they are often produced in the same areas. Some of the major areas that produce lead and zinc minerals include Australia, China, Peru, and the United States.
Which metal is more resistant to corrosion lead or zinc?
Zinc is generally more resistant to corrosion than lead. Zinc forms a protective oxide layer when exposed to the atmosphere, which helps prevent further corrosion. In contrast, lead can corrode under certain conditions, especially in acidic environments. Therefore, zinc is often preferred for applications requiring corrosion resistance.
What is Broken Hill most famous for?
Broken Hill is a mining town in the far west of New South Wales. It is most famous for silver, lead and zinc, though other metals are also mined there.
Broken Hill mining site?
Broken Hill was first identified as a mining site in 1883 by Charles Rasp. It was later discovered to be the richest desposit of silver, lead and zinc in the world. Broken Hill. Broken Hill has been mined continuously for 125 years.
What is the major ore minerals mined at Broken Hill mine?
The major ore minerals mined at Broken Hill mine are galena (lead sulfide) and sphalerite (zinc sulfide). These minerals are rich in lead and zinc, making them valuable resources for production. Additionally, the ore at Broken Hill mine may also contain silver and other minerals as byproducts.
When and where was zinc first mined in Australia?
Zinc was first mined in Australia at Broken Hill in 1883. Either Broken Hill, or Mt Isa, one or the other...
Name one metal mined at Broken Hill?
The town of Broken Hill in far west NSW, Australia, is home to the richest deposits of silver, lead and zinc in the world. Because of its rich mining history, Australia's Broken Hill Proprietary Company (joined with Billiton to become BHP-Billiton) now has extensive mines in many countries.
What is Mt Isa famous for producing?
The city of Mt Isa in western Queensland is famous for its mining of copper, lead, zinc and silver.
Does zinc contain lead?
No, zinc does not contain lead. Zinc and lead are two different elements with distinct chemical properties.
Why is zinc used in desilverisation of lead?
Zinc is used in the desilverization of lead because zinc has a higher affinity for silver than lead does. When zinc is added to molten lead containing silver, zinc combines with silver to form a zinc-silver alloy, which then floats to the surface for easy removal, leaving behind lead that is desilverized.

Zinc being less dense can be continuously removed from the top layers.
Where is zinc Mined in Australia?
Zinc is always found in combination with lead and silver. The largest lead-zinc-silver mine in Australia is Mount Isa, producing about 4.5 million tonnes silver-lead-zinc ore per annum with concentrations of: 154g/t silver 5.4% lead 6.5% zinc
What is melting point of zinc and lead?
The melting point of zinc is 419.5°C, while the melting point of lead is 327.5°C.
What is the lead are zinc ore industry?
This category covers establishments primarily engaged in mining, milling, or other wise preparing lead ores, zinc ores, or lead-zinc ores
