Mosaic South Pasture Mine, Florida

Mosaic’s South Pasture Mine is the third largest of its four active mines in the Bone Valley, producing around 2.8 million tons per year. It is one of a few phosphate mines and plants that Mosaic acquired from CF Industries in 2014, when CF sold its phosphate and potash facilities, to focus on nitrogen. Mosaic is a new company made up of old companies, formed in 2004 by merging Cargill’s crop nutrition division and IMC Global, both of which were already among the largest fertilizer companies in the nation. Headquarters are in Plymouth, Minnesota, just a couple miles up the road from the headquarters of Cargill, which remains the nation’s largest privately held company. The merger instantly created the largest US-based producer of potash and phosphate fertilizer.
