It's easy to see what phosphate mining can do to an ecosystem. Strip mining removes 20 to 40 feet of the surface of an area to get to the phosphate. In the process, the entire environmental system, including the surface and underground water flows; topography, animals and plants are changed. Large amounts of water are retained during the mining ...

Does 'reclaiming' old phosphate mines live up to the promise?
Phosphate mining is strip-mining that clears the land in sections. First, 30 to 40 feet of "overburden" and then 15 to 25 feet of phosphate-containing layer called the matrix are dredged away with a drag line. What's left is a landscape that looks otherworldly — a far cry from Florida's lush natural lands. Dark, dusty soil forms hills ...
