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 part of the Illinois fluorspar field known as the Cave in Rock district is characterized by horizontal deposits of fluorspar that have been formed by re­ placement of certain limestone beds in the Mississippian series of rocks. Unlike the vein deposits of the rest of the field, the Cave in Rock deposits occur at

OUR PROJECT. Canada Fluorspar (NL) Inc. (CFI), a company owned by Golden Gate Capital, is planning to develop the St. Lawrence Fluorspar Project in St. Lawrence, Newfoundland and Labrador, Canada. CFI will mine high quality fluorspar ore from the AGS Vein, produce acid-grade fluorspar concentrate, and export the product to …

Fluorspar, Uranium, and Beryllium Deposits at Spor Mountain and Historical Overview of the Discovery and Geology of the Topaz Mountains, Utah. G.M. Park. Abstract. Three mineral exploration booms in the Topaz Mountains have discovered economic deposits of fluorspar in the 1940s, uranium in the 1950s, and beryllium in 1959. In 1937, Fay Spor ...

The studies of fluorspar localities in Utah made by the U. S. Geological Survey during and since the recent war are summarized. The fluorspar at the Cougar Spar and Blue Bell mines in the Indian Peak Range of western Beaver County occurs as fissure veins in fault and breccia zones in volcanic and intrusive rocks. At the Monarch (Staats) claims in west …

The fault systems of the Levias-Keystone and Dike-Eaton areas, in the Kentucky-Illinois fiuorspar district, are a complex northeastward-trending sys- tem and a simple northwestward-trending system of steeply dipping normal faults, associated in part with a lamprophyre dike. Fluorspar mining started in the area about 1900 and, as of 1945, …

August 28, 2010. Fluorine (F) is a widespread element that was deposited in a variety of rocks, minerals, and geologic environments in central Colorado. It occurs as a trace element, as a major component of the mineral fluorite (CaFs), and as a major economic source of fluorine in fluorspar deposits, which are massive concentrations of fluorite.

INTRODUCTION. Nearly 40 percent of the more than 200 fluorspar mines, prospects, and occurrences in New Mexico occur within or along the margins of the Rio Grande rift system. Numerous deposits occur within or marginal to the zone in Sierra, Luna and Grant counties, and there are several occurrences in Dona Ana and Socorro counties. There are a ...

Fluorspar in Kenya. Fluorspar, a mineral-rich in fluorine, has quietly become a significant player in Kenya's mineral industry. In this article, we'll delve into the world of fluorspar in Kenya, exploring its geological significance, economic impact, and its role on the global stage.

KGS and the U.S. Geological Survey mapped the district at a scale of 1:24,000, and KGS has converted these maps into digital format for the Kentucky portion of the fluorspar district. The KGS Minerals Database contains abundant information on all of the ore deposits in the Western Kentucky Fluorspar District. History and Production

Later, the Geological Survey of Uganda carried out a pitting and drilling programme on the northern slopes of Nkokonjeru and located various sub-horizontal sediments classified as 'calcareous ...

A nodular type of fluorspar probably formed by alternate rotation of fragments of breccia and deposition of fluorite.Regional zoning is shown by the distribution of barite and green fluorite. Barite shows a distinct zone of localization, and green fluorite predominates in veins both near the granite margins and farther from the granite body ...

This report provides a historical snapshot of how the war drove the need for certain ores and what was done to locate and assess them: it presents the information gathered in the search for fluorspar. From the Preface: During the spring and early summer of 1917 ...

Most of the minerals came from Ben E. Clement, a miner that arrived in Kentucky in the early 20th century dreaming of operating his own fluorspar business. The minerals produced from his mines ...

The fluorspar is known to occur through a vertical . range of more than 600 feet, and as the deposits are discon­ tinuous vertically as well as horizontally, fluorspar bodies ... GEOLOGY AND FLUORSPAR DEPOSITS . were worked for fluorspar. The mineralogy and paragenesis . of.the pegmatite dikes were discussed briefly by Landes. 4 . in .

Displace ments in the area mapped range from a few feet to more than 1,500 feet. Detailed geologic mapping of the surface and data from underground work-^ ings have revealed …

Fluorspar was deposited throughout a vertical range of 600 feet or more on each of the main vein zones, and for a vertical range of 1,050 feet for the district as a whole. None of the deposits had been bottomed at the time this report was prepared. Exploration at depth beneath known ore bodies is favorable for developing large tonnages of ...

Most fluorite occurs as vein fillings in rocks that have been subjected to hydrothermal activity. These veins often contain metallic ores which can include sulfides of tin, silver, lead, zinc, copper, and other metals. Fluorite is also found in the fractures and vugs of some limestones … See more

Extensive secondary leaching and hydration-dehydration has led to classical colloidal textures. The gossan is a replacement after magnetite and siderite. Below the oxidation zone the ore consists of fresh magnetite-siderite-grunerite-fluorite and sulfides. Local vertical fracture zones exist with a prominent north-northwest orientation.

In cross section, the mantos are trough- or saucer-shaped, with the ore in the center of the trough ranging from 2 - 15 ft in thickness. The fluorspar is coarse-grained and typically grades 70-90% CaF 2 . The only gangue minerals are calcite and celestite. It is postulated that the deposits are hydrothermal and originated by introduction of F ...
