The Mosaic Company is the world`s leading integrated producer and marketer of concentrated phosphate and potash. We employ nearly 9,000 people in six countries and participate in every aspect of crop nutrition development. We mine phosphate rock from nearly 200,000 acres of Mosaic-owned land in Central Florida, and we mine potash from four mines in North America, primarily in Saskatchewan. Our products are processed into crop nutrients, and then shipped via rail, barge and ocean-going vessel to our customers in the major agricultural centers of the world. The work of mining and processing potash and phosphate minerals is an energy- and water-intensive endeavor. We work carefully to maximize efficiencies and minimize our use of energy and natural resources, and have made significant progress in reducing Mosaic’s environmental footprint.
Mosaic is a leader in the potash industry with annual capacity of 10.5 million tonnes of product per year, which accounts for approximately 12% of world annual capacity and 41% of North American annual capacity. Production during 2015 totaled 8.4 million tonnes, or approximately 13% of estimated world annual production and 43% of estimated North American annual production.
In 2015, we operated three potash mines in Canada, including two shaft mines with a total of three production shafts and one solution mine, as well as one potash shaft mine in the United States. We also own related refineries at each of the mines. Construction of our new Saskatchewan potash operation, Esterhazy K3, remains on budget, on time and on track to start producing ore in 2017. Following ramp-up, Esterhazy K3 is expected to add an estimated 0.9 million tonnes to our annual potash operational capacity.
With annual capacity greater than the next two largest producers combined, Mosaic is one of the world’s largest producers of finished phosphate products. We own and operate mines and production facilities in Florida which produce concentrated phosphate crop nutrients and phosphate-based animal feed ingredients, and processing plants in Louisiana, which produce concentrated phosphate crop nutrients.
Our U.S. phosphates operations have capacity to produce approximately 5.3 million tonnes of phosphoric acid, and approximately 17.2 million tonnes of phosphate rock, the key mineral used to produce phosphate crop nutrients and feed phosphate. Approximately one-third of our phosphate products are shipped within North America, with the remainder exported globally through our own distribution channels.
Mosaic is a young company rooted in history and experience. Recognized as innovators in our field, this status owes much to the combined strengths of the crop nutrition business of Cargill, Inc. and IMC Global Inc., our founding companies. Each of these companies has been recognized as worldwide leaders in the crop nutrition industry for decades. In 2014, Mosaic completed its acquisition of the phosphate business of CF Industries, Inc., and Archer Daniels Midland Company's fertilizer distribution business in Brazil and Paraguay.
IMC Global dates back to 1909, when entrepreneur Thomas Meadows became involved in the phosphate mining business. In 1940, the company mined 50,000 tonnes of potash from its Carlsbad, N.M., plant. IMC Global mined approximately 1.7 million tonnes in the same location in 2003, helping the company earn $2.2 billion in revenue.
A grain backhaul opportunity launched the crop nutrition business of Cargill in the 1960s. Product was needed to fill empty barges to make a profitable roundtrip, so Cargill — already a leading agribusiness company — entered the crop nutrition business. From there, the division grew to be one of the world's top producers of phosphate and nitrogen fertilizer.
Today, Mosaic is the world's leading producer and marketer of concentrated phosphate and potash. We employ nearly 9,000 people in six countries and participate in every aspect of crop nutrition development.
