Mining a Pegmatite Actforlibraries.org

Mining a pegmatite is like butchering a hog these is a demand for practically everything you find. The most important mineral is feldspar that has many uses un both industry as a mild abrasive, and the home as a cleaning product such as scrubbing powder. Mica is probably the most important. The quartz is the next to go; this is first etched

Harding Pegmatite Mine Wikipedia

Although the quartz pegmatite had attracted the attention of prospectors since before 1900, the extensive deposits of lepidolite were not recognized until 1918 by Joseph J. Peyer. Peyer and his partners mined the ore body with explosives, sorted the ore by hand, and hauled the ore to Embudo by wagon, where the nearest rail line was located. At that time, the chief use of lithium was in specialty glass. However, the ore was contaminated with unrecognized tantalitewhich caused serious difficulties with its use, and producti
