- Mining And Processing Of Iron Gold And Phosphate
A century later, Florida's phosphate miners are highly trained technicians who sit in air-conditioned, 8-million-pound excavators. They unearth some 10 million tons of phosphate rock a year, supplying nearly a quarter of global demand for the "white gold" that helps crops grow.. Florida is home to one of the richest phosphate deposits in the world.
