Lead / Galena
What is it and where is it formed? Galena is the main ore of lead and silver. It is a combination of lead and sulfur. Galena is found combined with zinc, copper, and silver. It is sometimes considered a by-product of the mining of the other minerals. When the ore is melted, it makes lead. It is formed in the earth’s crust in hot water veins. Galena is found in igneous and sedimentary rocks.
How and where is it mined? Galena is found with underground mining. It is found in the U.S.A [Texas, Oklahoma, Missouri], Germany, Peru, Mexico, Zambia, and England.
What is it used for? Galena is used in things that are made of lead. Some of these things are: bullets, batteries, gasoline, paint, and welding solder. Lead used to be put in paint, dishes, and cups until it was found that it was poisonous when it was swallowed. Sometimes kids would chew on painted things because lead gave the paint a sweet taste. This would make the kids really sick so it isn’t used for this anymore.
Lead was the first metal mined in Australia, at Glen Osmond in South Australia in 1841, after the wheel of a cart being pulled up a rough track accidentally exposed some lead-zinc ore! The ores of lead (mainly galena, which is lead sulphide) usually occur together with other ores. The discovery of a large lead-zinc-silver orebody at Broken Hill in 1883 (a mine is still in operation today) was a significant event in Australia's history as it greatly boosted our economy. Previously we had relied only on wool and wheat for the nation's wealth.
Today, Australia is the world's leading producer and exporter of lead, with large mines at Broken Hill, Mt Isa and Hilton in Queensland, and McArthur River in the Northern Territory. However, more than half of the lead we use comes from recycling, mostly from old car batteries.
Most lead mines are underground operations. The lead ore is blasted, scooped up by front-end loaders, taken in large trucks to underground crushers, then hoisted to the surface up one of the shafts. At the surface, the ore is crushed further and subjected to the froth flotation method, then heated and treated in other ways to purify the lead and separate it from any other metals. Our lead refinery is at Port Pirie in South Australia.
Shanghai Zenith company provide Australia with lead/galena crushing plants for extracting lead minerals. The cruhsing plants work on the ground and fixed by steels. If you exploitate the minerals underground , you need explode and take them over the ground. Then it's the crushing plant that process the stones and rocks-- Crushing and grinding. The galena crushing plants are very famous in Australia as the Lead On company which is the most famous lead mining company in Australia take the Zenith crushing plants. Jaw crusher and cone crusher is the recommanded crusher for lead or galena crushing. The feature is high crushing ratio and low cost.
