Anglesite
Chemical Composition
Anglesite is a lead sulfate mineral with the chemical formula PbSO₄. It is commonly found as a secondary mineral in lead deposits.
Origin and Location
Anglesite forms in oxidized zones of lead ore deposits. It has been found in locations like the United States, Mexico, and Morocco.
Uses and Applications
Anglesite has limited industrial use, primarily as a source of lead for lead-based alloys and in the production of lead salts.
History and Discovery
Anglesite was first discovered in the 19th century in the Anglesey region of Wales, where its name originates.
Physical Properties
Anglesite has a hardness of 2.5 to 3 on the Mohs scale. It is usually colorless, white, or gray and forms tabular crystals or granular masses.
Formation Process
Anglesite forms in oxidized zones of lead deposits, usually in arid environments, through the alteration of other lead minerals like galena.
Optical Properties
Anglesite crystals are transparent to translucent, with a glassy to adamantine luster. It exhibits perfect cleavage in one direction.
Classification
Anglesite is classified as a sulfate mineral and is a secondary mineral found in lead deposits.
Interesting Facts
Anglesite is often found alongside other lead minerals like galena and cerussite. It is toxic due to its lead content and should be handled with care.
