The World's three largest producers of fluorite from carbonatite-related fluorspar ore deposits are located at Okorusu (Namibia), Amba Dongar (India), and Mato Preto (Brazil). Beneficiation problems involving fluorite concentrates from those three deposits share similar characteristics that are directly related to the mineralogy and textures of the ores. …

Recent field mapping in two open pits at the Okorusu fluorspar mine in Namibia confirmed the presence of a variety of host rocks that were replaced by fluorite ores. The presence of certain textures in the fluorite ores can be used to identify the original host rock that was replaced. The character of the original host rock prior to fluorite replacement, in turn, has …

Fluorine compounds are essential in numerous chemical and manufacturing processes. Fluorspar is the commercial name for fluorite (isometric CaF2), which is the only fluorine mineral that is mined on a large scale. Fluorspar is used directly as a fluxing material and as an additive in different manufacturing processes. It is the source of fluorine in the …

The story of fluorspar started in the late 1960s, when an independent local mineral prospector, M Al-Amin, discovered rich fluorspar deposits in the Kerio Valley. How he was swindled and pushed out is the untold story of fluorspar mining, and it explains how Kenya failed to build a local industry based on one man's dreams.

Once the ore is exposed, it is then drilled, blasted, and loaded onto trucks for transportation to the processing plant. Underground mining is another method used to extract fluorspar ore, especially when the ore deposits are located deep underground. In underground mining, tunnels are dug into the earth to access the fluorspar ore.
