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, …

The REE characteristics of barite and fluorite have close relationships, in regard to the source of ore-forming materials, to the Lower Cambrian Niutitang Formation black shales.

A845 was also tested in flotation of high-grade barite from complex ferrous ore from an ore deposit in Kremikovtzi, Bulgaria. It was found that a 2:1 ratio at a total consumption of 400–450 g/t of OMC 199 and AERO 845 in the presence of WG (4–4.5 kg/t) and OrePrep F501 as frother (10–15 g/t) was able to recover 77–98 % of Ba(Sr)SO4 ...

The mineralogy of the deposits is relatively simple, with the main ore minerals being fluorite, barite and bastnäsite.The fluorite occurs typically as subhedral, coarse-grained aggregates in the fault zones, sometimes as fluorite masses with rare colour-banding, less frequently cubic, and octahedral or rhombdodecahedral shape. ...
