Fluorite is very easy to identify if you consider cleavage, hardness, and specific gravity. It is the only common mineral that has four directions of perfect cleavage, often breaking into pieces with the shape of an octahedron. It is also the mineral used for a hardness of four in the Mohs Hardness ...
Silver is an extremely soft, ductile and malleable transition metal, though it is slightly less malleable than gold. Silver crystallizes in a face-centered cubic lattice with bulk coordination number 12, where only the single 5s electron is delocalized, similarly to copper and gold.
Fluorite (also called fluorspar) is the mineral form of calcium fluoride, CaF2. It belongs to the halide minerals. It crystallizes in isometric cubic habit, although octahedral and more complex isometric forms are not uncommon.
Mineral Resources of the Illinois-Kentucky Mining District By DARRELL M. PINCKNEY GEOLOGICAL SURVEY PROFESSIONAL PAPER 970 Excellent possibilities exist for finding deposits of fluorspar, lead, zinc, silver, cadmium, rare earths, and niobium in Illinois and Kentucky UNITED STATES GOVERNMENT PRINTING OFFICE, WASHINGTON 1976
Silver is a soft, white metal that usually occurs in nature in one of four forms: 1) as a native element; 2) as a primary constituent in silver minerals; 3) as a natural alloy with other metals; and, 4) as a trace to minor constituent in the ores of other metals. Most of the silver produced today is a product of the fourth type of occurrence.
The Magic of Rocks and Stones. Fluorite (Fluorospar or Fluor Spar). Written and compiled by - Patricia Jean Martin. Fluorite, a mineral that melts easily, derives its name from the Latin word "fluere" meaning "to flow" or "to flux" and refers to its use as a flux in the steel and aluminum smelting process.

Fluorine is a chemical element with the symbol F and atomic number 9. It is the lightest halogen and exists as a highly toxic pale yellow diatomic gas at standard conditions.As the most electronegative element, it is extremely reactive, as it reacts with almost all other elements, except for helium and neon.
The Kentucky portion of this district is called the Western Kentucky Fluorspar District. Until the 1970s, more than three-fourths of the fluorspar produced in the United States came from the Illinois-Kentucky Fluorspar District, which was the largest producer of fluorite in the United States during World War II.
Fluorite is a widely occurring mineral that occurs globally with significant deposits in over 9,000 areas. It may occur as a vein deposit, especially with metallic minerals, where it often forms a part of the gangue (the surrounding "host-rock" in which valuable minerals occur) and may be associated with galena, sphalerite, barite, quartz, and calcite.
Veins are mineral deposits which form when a preexisting fracture or fissure within a host rock is filled with new mineral material. Hydrothermal deposits are categorized according to the depth and temperature at which they formed.
One of the most famous of the older-known localities of fluorite is Castleton in Derbyshire England, where, under the name of Derbyshire Blue John, purple-blue fluorite was extracted from several mines or caves, including the famous Blue John Cavern. During the 19th century, this attractive fluorite was mined for its ornamental value.

of fluorite. These tailings contain up to 3% fluorite, which was a common gangue mineral in the lead–zinc ore. Attempts in the early 1960s to extract fluorite from the tailings on a commercial basis were unsuccessful (MacNevin & Dawood 1973). Possible Mississippi Valley type mineralisation has been discovered at Wonowinta or Blue Mountain, west

Fluorite is considered to be one of most popular minerals in the world among gem and mineral collectors, second only to quartz. It is often referred to as 'the most colorful mineral in the world' owing to its variety of brilliant colors. Fluorite was first described in 1530 and was originally referred to as 'fluorspar'.
