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.

Chemical Processing of Phosphate. The phosphate mineral as it exists in the ground is not soluble and is hard for the plant to access. To provide the plant with the phosphate it needs, in a form it can take up through its roots, the phosphate rock is converted to phosphoric acid. It is that acid that is used to make fertilizer.
