Rather, a whole range of rocks geologically connected to granite are used. Most often, commercial feldspar is mined from pegmatite or feldspathic sand deposits. Aplite, which is a fine-grained igneous rock with the same mineralogical composition as granite, also is mined frequently for its feldspar …
Feldspar minerals are essential components in igneous, metamorphic and sedimentary rocks, to such an extent that the classification of a number of rocks is based on their feldspar content. Although highly present in igneous rocks like granite, commercial feldspar is generally mined from pegmatite or feldspathic sand deposits.

Georgia, Idaho, Oklahoma and South Dakota made up the remainder. World mine production of feldspar was an estimated 20 million metric tons in 2010.
Feldspar is mined from large granite bodies (called plutons by geologists), from pegmatites (formed when the last fluid stages of a crystallizing granite becomes concentrated in small liquid and vapor-rich pockets that allow the growth of extremely large crystals), and from sands composed mostly of feldspar.
Mar 25, 2011· If you love Maine minerals and/or gemstones, just be thankful that there was an active feldspar industry up through the 1950's in Maine exposing many of the things that we treasure today. Some of the minerals and gems were just a waste product to the feldspar mining.
