Lead is chiefly obtained from the mineral galena (lead sulfide). Other common lead-bearing minerals include anglesite (lead sulfate), boulangerite, cerussite, (lead carbonate), minim and pyromorphite. It is mined in Australia, the USA, Canada, China and Peru.

Hydrothermal mineral deposit - Wikipedia

Hydrothermal mineral deposits are accumulations of valuable minerals which formed from hot waters circulating in Earth's crust through fractures. They eventually create rich-metallic fluids concentrated in a selected volume of rock, which become supersaturated and then precipitate ore minerals.In some occurrences, minerals can be extracted at a profit by mining.

Galena Mineral | Uses and Properties

Uses of Galena. Galena is a very important mineral because it serves as an ore for most of the world's lead production. It is also a significant ore of silver. Galena has very few uses beyond its service as an ore, but that should not diminish its importance to society.

The ore grade, or concentration of an ore mineral or metal, as well as its form of occurrence, will directly affect the costs associated with mining the ore. The cost of extraction must thus be weighed against the metal value contained in the rock to determine what ore can be processed and what ore

Lead (Galena) Facts

Lead is a naturally occurring metallic element usually associated with other ore minerals (primarily those of zinc, silver and copper) such as pyrite, sphalerite, quartz and barite.Trace amounts of other elements including gold are sometimes found with lead ore. The most common ore mineral of lead mined in the United States is galena with the chemical symbol PbS.

Galena - Wikipedia

Galena also was a major mineral of the zinc-lead mines of the tri-state district around Joplin in southwestern Missouri and the adjoining areas of Kansas and Oklahoma. Galena is also an important ore mineral in the silver mining regions of Colorado, Idaho, Utah and Montana.

Lead: smelting, producing and classification-Metalpedia

The majority of the deposits are mixtures of minerals, hence lead ore is usually obtained as a byproduct of other metal mining such as zinc, silver or copper. In fact, lead ore is a main source of silver and contributes substantially towards the world's total output. The most common lead ore is galena (PbS), which contains 86.6% lead.

Galena - Wikipedia

The main lead-bearing mineral is galena (PbS), which is mostly found with zinc ores. Most other lead minerals are related to galena in some way; boulangerite, Pb 5 Sb 4 S 11, is a mixed sulfide derived from galena; anglesite, PbSO 4, is a product of galena oxidation; and cerussite or white lead ore, PbCO 3, is a decomposition product of galena.

Missouri Lead Mining History by County - DNR

Early mining in the entire southeast Missouri area was of oxidized ores, primarily the lead carbonate mineral cerussite. Mining moved onto galena when the more easily smelted cerussite was depleted. Numerous small mines produced as much as 1,500 pounds a day of ore.

Lead: Mineral information, data and localities.

Native lead is rare; lead is far more commonly found and mined as the lead sulphide mineral galena. The Romans named the refined metal 'plumbum' and used it for pipes in plumbing. Its major use today is in lead-acid batteries and for radiation shields. It is also a constituent of low-melting alloys. Native lead is somewhat ductile and very ...

How Is Lead Mined? |

Lead ore comes from underground mining operations, where the lead ore seams are blasted out of the ground and transported to the surface for refinement. Lead is commonly found in deposits with other minerals, such as silver, zinc or copper.

Lead - Essential Chemical Industry

(a) Ore concentration. Lead and zinc ores (usually sphalerite, ZnS) often occur together and may also contain silver, copper and gold. The ore has first to be separated from clays and other silicates ('gangue') after which the lead ore and the zinc ore are separated.

Uses of Lead | Lead Deposits and Resources

Research to better understand the geologic processes that form mineral deposits, including those containing lead, is an important component of the USGS Mineral Resources Program. Lead commonly occurs in mineral deposits along with other base metals, such as copper and zinc. Lead deposits are broadly classified on the basis of how they are formed.
