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 …
Exploration is intermittent in the district, and currently there is one operating mine, the Klondike II, in Livingston County. Zinc has been produced for many years in a couple of veins such as the Hutson and Old Jim, and around 1940 the district became a major source of zinc, some as a byproduct of fluorite mining, some as a main product.
A tiny crystal of highly-reactive fluorite. Credit: Parent Gery under CCBYNC2.0. Fluorine is a relatively soluble and highly reactive found within fluorite. Exposure to the chemical can lead to a severe bone disease called skeletal fluorosis, which weakens bones. In China, coal mining has caused more than 20 million people to suffer …

In terms of fluorite ore beneficiation, stage grinding, stage separation, and multiple beneficiation are the main processes of fluorite ore flotation. The process flow design and mining equipment configuration of the fluorite ore dressing plant need to be designed according to the actual situation.
The term "fluorspar" refers to crude or beneficiated material that is mined and/or milled for the mineral fluorite (calcium fluoride). Fluorite is a nonmetallic mineral, containing 51.1 percent calcium and 48.9 percent fluorine. Industry practice has established three grades of fluorspar: acid grade (containing more than 97 percent calcium ...
The main gangue minerals found in the Bayan Obo ore are quartz, apatite, dolomite, and fluorite. Mining at Bayan Obo ... The ore material from the mine site is sent to Baotou for processing.
