Mosaic Riverview Plant, Florida

Phosphate mining stops a few miles east of Tampa Bay and the City of Tampa, but the handling and processing of phosphates occurs around the shore, especially at Mosaic’s Riverview Facility on Tampa Bay. The plant is similar to the two operating in the Bone Valley, a few miles east, and every year produces 800,000 tons of phosphoric acid and 1.6 million tons of processed phosphate from phosphate rock extracted in the valley. Like the other plants, Riverview stacks its main waste product, phosphogypsum, in a mound next to the facility, making a gypstack that covers more than a square mile.
