Argutite is a rare mineral that was first discovered in Germany in the 19th century. It is a silvery-grey, metallic mineral that is often found in association with other tungsten-bearing minerals. Synonyms for argutite include tungstenite, wolframite, ferberite, and huebnerite. Tungstenite is a mineral that contains both tungsten and iron and is often found in hydrothermal veins. Wolframite is a commonly occurring mineral that is often used as an ore of tungsten. Ferberite is a tungsten-bearing mineral that is often found in pegmatites and tin deposits. Huebnerite is a tungsten-bearing mineral that is often found in high-temperature hydrothermal veins. These minerals are all essential to the production of tungsten, which is used in many of our everyday items.
