Fluorspar Statistics and Information - USGS

More than half of the mined fluorspar came from veins composed mainly of fluorite and calcite. The ore bodies are the result of fissure filling with some replacement of the early vein material and wallrock. Residual concentrations of high-grade fluorspar in the overburden along faults also have yielded considerable quantities of "gravel" fluorspar.

Fluorspar Deposits of Utah - USGS

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 information of some of the known fluorite ...

Apr 10, 1972· although fluorspar deposits occur in all kinds of host rocks. Ground preparation is very important for the formation of fluorspar deposits; faults and fractures provide passageways for the fluorine-bearing fluids. Brecciated zones, especially those capped by imperme-able rocks, provide sites favorable for voidfilling and - replacement deposits.

Hydrothermal mineral deposits are accumulations of valuable minerals which formed from hot waters circulating in Earth's crust through fractures. They eventually create rich-metallic fluids concentrated in a selected volume of rock, which become supersaturated and then precipitate ore minerals.In some occurrences, minerals can be extracted at a profit by mining.

Mineral Resource of the Month: Fluorspar | EARTH Magazine

neous rocks are common associates of fluorspar deposits, but any type of rock may act as the host for the actual deposit; limestone and dolomite are most fa-vorable. Most large concentrations of fluorite are associated with continental rifts and lineaments throughout the world [17].

Quaternary Fault and Fold Database of the United States

The replacement style is interpreted to have a stronger potential for fluorite enrichment (i.e. higher grades). Based on the assays to date, the fluorspar is found to be associated with moderate grades of niobium, tantalum, and phosphate, each considered to be a potentially recoverable commodity in this geological setting.

Fluorspar replacement deposits in limestone at contacts with the rhyolites contain as much as 38,000 ppm Zr, occurring as small, disseminated zircons. The deposits also are enriched in a variety of incompatible elements, including Be, rare-earth elements (REE), Y, Nb, Mo, Hf, Pb, Th and U.

FLUORINE RESOURCES IN NORTH AMERICA

Deposits in limestone and dolomite are formed either by replacement or by a combination of replacement and fissure filling. Because replacement results in the removal of much of the gangue material, mineable grade fluorspar ore is more common in replacement deposits than in fissure-filling deposits, TABLE 1,

New Mexico Bureau of Mines & Mineral Resources

Fluorspar, or fluorite, occurs in a variety of geological environments and is deposited under a wide range of chemical and physical conditions, but commercial sources are primarily hydrothermal. The most common deposits occur as veins, mantos (replacement strata-bound orebodies) or replacement deposits. Other important deposits include stockworks and fillings in shattered zones, carbonatite ...

Sizeable quantities of lead, zinc, silver, barite, and other minerals also were mined from vein and bedded-replacement deposits. The Fluorspar Area Fault Complex overlies the junction area of a Proterozoic-Cambrian failed rift complex that consists of the northeast-trending Reelfoot rift and the east-trending Rough Creek graben.

Fluorspar - an overview | ScienceDirect Topics

Fluorspar is used directly or indirectly to manufacture products such as aluminum, gasoline, insulating foams, refrigerants, steel, and uranium fuel. Byproduct fluorosilicic acid production from some phosphoric acid producers supplements fluorspar as a domestic source of fluorine, but is not included in fluorspar production or consumption calculations.
