The Industrial Might of Connecticut Pegmatite

To help make the operation profitable, the Feldspar Corporation mined both quarries for quartz and mica, as well as feldspar, and used the flotation separation technology developed in the 20th century that allowed minerals in pegmatite to be sorted more easily and cost effectively.

Feldspar - Sandatlas

Feldspar is the most abundant mineral group in the Earth's crust. There are more feldspars (60%) than all the other minerals combined in the outer (13-17) km of the crust 1. Feldspars occur in most igneous and metamorphic rocks. They are less common in sedimentary rocks as they tend to break down to clay minerals in the weathering environment.
