The mine is located in Richland Township, in Aurora in Beaufort County, North Carolina. [2] The mine, has been owned by PotashCorp since 1995, has an annual production capacity of over six million tonnes of phosphate ore. [2] In 2008 the mine produced 6.6 million tonnes of phosphate ore from which 1.3 million tonnes of phosphoric acid was ...
Today, the mine produces around 3 million tonnes annually, which represents 10% of Morocco's total production. [3] The phosphates are transported to the coast by an automated conveyor belt . Approximately 100 kilometres (62 mi) long, the belt is the longest in the world and dust blown from it is visible from space.
The phosphate mining industry employed 2,200 people. The value of phosphate rock mined was US$2.2 billion. As of 2015, there are 10 active phosphate mines in four states: Florida, North Carolina, Idaho, and Utah. The eastern phosphate deposits are mined from open pits. The western deposits are mined from both surface and underground mines.
The pits are filled with mine tailings where small shell, coral, shark tooth and other fossils are relatively easy to find. The pits are open during daylight hours daily. [2] [3] The museum provides information about the geological history of the Aurora area, which is known as a center for fossil hunting (especially due to the phosphate mine). [4]

Rotary gondolas such as these are used by CSXT to transport phosphate rock from the Bone Valley region to transloading facilities along Tampa Bay -- Edison, Florida.. Large walking draglines, operating twenty-four hours a day in surface mines, excavate raw pebble phosphate mixed with clay and sand (known as matrix).
The Phosphate Mine was in production from 1914 to 1918 however only 6000 tons of rock with limited amounts of phosphate were removed. The mine passages, mostly backfilled and collapsed, lay dormant for almost 80 years until they were reconstructed and reopened for tours in 1996.
Phosphogypsum is a by-product from the production of phosphoric acid by treating phosphate ore with sulfuric acid according to the following reaction: . Ca 5 (PO 4) 3 X + 5 H 2 SO 4 + 10 H 2 O → 3 H 3 PO 4 + 5 (CaSO 4 · 2 H 2 O) + HX
