Wolframite is a mineral composed primarily of iron, manganese, and tungsten. It is an important ore for extracting tungsten, a metal known for its high melting point and strength. Wolframite typically appears in dark brown to black colors and has a metallic luster, making it easily recognizable. This mineral is often found in granite and quartz veins, as well as in alluvial deposits. Mining for wolframite occurs in various countries, including China, Portugal, and Bolivia. The extraction of wolframite is crucial for industries that rely on tungsten for applications such as electrical contacts, filaments, and cutting tools.
