Mineral resource of the month: feldspar




The United States is the third leading producer of feldspar worldwide, after Italy and Turkey, according to data published by the U.S. Geological Survey. Foreign analysts indicate that China is also a leading feldspar producer, but official production data are not available. Feldspars are aluminum silicate minerals that contain varying proportions of calcium, potassium and sodium. Usually occurring in igneous rocks, feldspars are estimated to constitute 60 percent of Earth’s crust.
