Wulfenite: Background and Summary

Wulfenite is a mineral that is commonly found in the oxidation zones of lead and zinc deposits. It is known for its unique orange, yellow, and red coloration, which makes it a popular mineral among collectors. Wulfenite is composed of lead molybdate, and it has a hardness of 3 to 3.5 on the Mohs scale.

One of the easiest ways to identify wulfenite is by its color and crystal habit. Wulfenite crystals typically form as square or rectangular prisms, which are often found in clusters. The mineral's bright orange, yellow, and red coloration is due to the presence of lead and molybdenum ions in its crystal lattice. When viewed under a microscope, wulfenite crystals can also exhibit a distinct birefringence, which is caused by the mineral's anisotropic nature.

Wulfenite has several uses, including as a minor source of lead and molybdenum, as well as a collector's mineral. In some cases, wulfenite may be used as a gemstone, although it is not commonly used for this purpose. The mineral is also used in the production of pigments, ceramics, and glass.
