Fluorspar is sold in two different grades: Acid grade fluorspar (acidspar) – a high-purity material used by the chemical industry. It contains over 97% CaF 2. Most of the fluorspar consumed in the USA is acid grade even if it is used in lower grade applications. Acidspar is used mainly in the chemical industry to manufacture hydrofluoric acid.
Fluorite, also known as fluorspar, is a widely occurring mineral found in various geological settings around the world. It is a colorful and highly valued mineral due to its vibrant fluorescence when exposed to ultraviolet light, which gives it its name. Fluorite has a fascinating range of physical properties and has numerous industrial, scientific, …
