Tungsten minerals are naturally occurring compounds that contain the element tungsten, which is known for its high density and melting point. The most significant tungsten mineral is wolframite, a combination of iron and manganese tungstate. Another important mineral is scheelite, which contains calcium tungstate. These minerals are primarily found in granitic rocks and are often extracted through mining processes. Tungsten is essential in various industrial applications, particularly in the production of hard metals and alloys. It is widely used in the manufacturing of tungsten carbide, which is known for its hardness and durability. Additionally, tungsten is utilized in electrical contacts, filaments, and as a component in high-performance tools.
