A New Classification Scheme of Fluorite Deposits
Fluorite deposits occur in a variety of geologic environments throughout the globe. It may occur as the main or only economically recoverable ore mineral in deposits or may present as the accessory gangue minerals with other ores. It is therefore necessary to understand various genetic types of the fluorite deposit. The present paper synthesises the …

4 Steps to Process Complex Low-grade Fluorite Ore
The fluorite-quartz type ore is mainly composed of fluorite (with a content of up to 85%), quartz, and only a small amount of calcite, barite and sulfide. The quartz component of fluorite concentrate differs from different production classes, which can be divided into three classes, metallurgical-grade, ceramic grade, and acid grade.

Fluorite Stone
Originally called Fluorspar, this stone is said to consume negative energy and convert it into positive vibrations. It has a natural property which cleanses the aura and brings forth mental clarity. Fluorite is a softer stone, coming in at a 4 on the Mohs scale of hardness. Fluorite is also utilized as a source of fluorine for fluoridated water.

Reactive transport modeling of the role of fluorine-rich
The Illinois-Kentucky ore district hosts the largest deposits of fluorite in the USA. A long-standing hypothesis for the formation of the Illinois-Kentucky deposits is that the ore fluid was a sedimentary brine infused with F-rich fluids exsolved from Permian ultramafic magmas. This ore fluid may have had a F concentration between 680 and …
