The central Florida phosphate mining region covers approximately 1.3 million acres of land known as the "Bone Valley." There is one phosphate mine operating in North Florida (Hamilton County). Click for full-page map of Phosphate Mine Boundaries.
Does phosphate mining create radioactive phosphogypsum stacks? Phosphate mining does not create radiation. Phosphogypsum, a byproduct of the fertilizer manufacturing process, is produced when the phosphate rock we mine is combined with sulfuric …
Most mining is by open pits and strip mining and the rock requires little processing other the the removal of the non-phosphate bearing rock and other impurities. This process involves crushing and separating impurities (sediment, bones and shells) from the phosphate rock.
At Ma'aden, we mine phosphate rock and process it into phosphate products, including diammonium phosphate (DAP) and monoammonium phosphate (MAP), the most widely used phosphate fertilizers in modern agriculture. Our vision is to be among the leading players in the global phosphate trade.

In 1900 it took a year to mine a 15-acre mine site with picks and shovels. Today one dragline mines 15 acres in a month. Digging the phosphate out of the ground is only one step of the mining process. Phosphate comes out of the ground as part of a matrix, which is a mix of the phosphate, sand and clay.
