Most sheet mica is mined in India, where labor costs are comparatively low. Flake Mica Mining: The flake mica produced in the U.S. comes from several sources: the metamorphic rock called schist as a byproduct of processing feldspar and kaolin resources, from placer deposits, and from pegmatites. It is mined by conventional openpit methods.

Ironrich sedimentary rocks are sedimentary rocks which contain 15% or more iron.However, most sedimentary rocks contain iron in varying degrees. The majority of these rocks were deposited during specific geologic time periods: The Precambrian (3800 to 570 million years ago), the early Paleozoic (570 to 410 million years ago), and the middle to late Mesozoic (205 to 66 million years ago).
