2014-4-21 Sedimentary phosphate tends to be found in loose sediment, so it can be mined with dredge lines (or picks and shovels). In Florida, the phosphate is found mainly in one layer of clay and sand that’s about 10-20 feet thick, and 15-50 feet below the surface. After the heavy equipment digs out the overburden (the sediment above the desired layer), they remove and dump the phosphate-rich sediment into a pit. That sediment is mixed with pressurized water to make a slurry, and that slurry sent through miles of pipeline. Making and pressurizing the slurry requires a lot of electricity (15 kwh per ton of phosphoric acid) as well as water. Many phosphate mines
