rock type: sedimentary composition: grains of sand that can be feldspar or quartz the amount of other minerals, such as mica, depend on how much weathering has occurred. environment: already existing rocks are eroded and the grains are transported and sorted by rivers. the resulting sand is deposited on beaches, along floodplains or in deltas present mines worldwide are adequately meeting the need for raw feldspar. hard-rock mining for feldspars is done by open-pit methods, either by the mine owner or by contractors. after the feldspar ore is drilled and blasted, secondary breakage is performed with a conventional drop ball. ore is then loaded with a hydraulic shovel onto trucks and the maine feldspar co. leased the area in 1902 which resulted in the largest commercial mining excavation at mount apatite. feldspar was mined chiefly for the china and porcelain industry and was first transported to topsham and later two miles south to their processing plant, established in 1906, at littlefield station.
