The feldspar group minerals are the most abundant minerals in the earths crust. High concentrations of alumina (Al 2 O 3) and alkalis (K 2 O and Na 2 O) together with low levels of trace elements such as iron (reported as the oxide Fe 2 O 3) define a highquality feldspar adds hardness, durability and resistance to chemical corrosion while the alkalis act as a flux lowering

Relation to Mining. The top states producing feldspar are North Carolina, ia, California, Okloma, Ido, Georgia and South Dakota, in descending order of estimated tonnage. Feldspar processors reported coproduct recovery of mica and silica sand.

Feldspar. Obtained originally from pegmatites and granitic bodies, feldspar was first mined in North Carolina in 1911 in the Spruce Pine district, the primary feldsparproducing district in North America. Found largely in the Kings Mountain area of Mitchell County, the mineral is used to create a feldsparsilica concentrate during mica beneficiation.
Sep 18, 2012#0183;#32;Feldspar mining peaked in Connecticut in the early 1900s; in 1908 Connecticut, with its four spar mills, was the leading producer of this mineral in the United States. To collect feldspar, miners would drill holes in the pegmatite, fill them with black powder or dynamite, and blast the rock into chunks.

The White Rock Pegmatite Quarry Feldspar Mine is in Middletown, Connecticut. Historically the site has been part of the Middletown Mining District. The White Rock Pegmatite Quarry Feldspar Mine was closed at the time of data entry with no known plans to reopen. The New England Upland Section of the Appalachian Highlands characterize the geomorphology of the surrounding area.
Oct 02, 2019#0183;#32;The state remained the leader in gold mining until the California Gold Rush. Today, visitors and locals are still finding treasure. From gold to quartz and feldspar, the gems and minerals found in North Carolina mines are abundant and unique. In fact, Franklin is known as the Gem Capital of the World.
About 600,000 metric tons of feldspar is produced each year in the United States. Most of this feldspar is crushed into fine granules or powders and then consumed in factories that produce plate glass, ceramic tile, fiberglass insulation, paints, plastics, pottery, container glass and other products.

In glassmaking, feldspar provides alumina for improving hardness, durability, and resistance to chemical corrosion. In ceramics, feldspar is used as a flux, lowering the vitrifying temperature of a ceramic body during firing and forming a glassy phase. Glass and ceramics continued to be the major end uses of feldspar.
The Little Switzerland Business Association says the McKinney Mine was the largest feldspar mine in the world, and North Carolina was the largest producer. Feldspar had been discarded in the process of mining mica until William Dibbell sent a premium
Spruce Pine, NC. Spruce Pine is an idyllic mountain town located 780m above sea level in the Appalachian Mountains. It is here that The Quartz Corps North American headquarters and mining activities are located, all thanks to a unique geological event that took place 380 million years ago. It was this event that allowed some of the largest feldspar and mica crystals in the world to form.
Aug 04, 2019#0183;#32;The McKinney Mine near Little Switzerland was once the largest feldspar mine in the world, according to the Little Switzerland Business Association.

Mar 31, 2014#0183;#32;Luther Thomas, his late father and a local mining legend, was exempted from the draft in World War II because he needed to mine mica to produce radio tubes for the troops. I went to work when I was just 13 years old, driving steel in the feldspar mine with an eightpound sledge, Luther once told Charles Kuralt.
