Fluorite, also known as "Fluorspar", is a collectable, halide mineral comprised of calcium and fluorine. Fluorite occurs commonly in cubic, octahedral and dodecahedral crystals in many different colors. These colors range from colorless and completely transparent to yellow, green, blue, purple, pink or black.Purples and greens tend to be the most …

The mine will initially exploit two haematite-fluorspar ore-bodies, Outwash Fan and Plattekop, with an option to later include Wiltin, a proposed ore-body. At an average run-of-mine (ROM) rate of 30,000tpa, production of 185,000tpa of acid grade fluorspar and up to 30,000tpa of metallurgical grade fluorspar will be produced at the open-pit mine.

The use of fluorspar to produce fluorochemicals via a process that bypasses HF is highly desirable but remains an unsolved problem because of the prohibitive insolubility of CaF 2. Inspired by calcium phosphate biomineralization, we herein disclose a protocol of treating acid-grade fluorspar with dipotassium hydrogen phosphate (K 2 HPO …

Uranium can be found in the Earth's crust in different reservoirs, with igneous rocks being the primary source of this element from which many types of secondary deposits are formed. Fluorspar deposits generally do not contain uranium, but in some cases, fluorite can carry both uranium in solid solutions and inclusions of uranium minerals. We studied …
