We serve customers in approximately 40 countries. Business Developments during 2020•We continue to transform our cost structure. Phosphoric acid is produced by reacting finely ground phosphate rock with sulfuric acid. We extract phosphate ore from the Miski Mayo mine using excavators. We purchased approximately 3.6 million long tons of sulfur during 2020. Production of one tonne of DAP requires approximately 0.23 tonnes of ammonia. Ammonia is transported by pipeline from the terminals to our production facilities. We have included a discussion of ammonia prices in our Management's Analysis. We own related mills or refineries at our mines. In December 2020, we indefinitely idled our potash mine in Colonsay, Saskatchewan. Also, as part of the Acquisition, we acquired a potash project in Kronau, Saskatchewan. 11Table of ContentsThe map below shows the location of each of our potash mines. Production during 2020 totaled 8.4 million tonnes. In addition, we are expanding our Esterhazy mine for the K3 shaft. Extensive potash deposits are found in the southern half of the Province of Saskatchewan. At the Carlsbad facility, we mine and refine potash from 77,221 acres of mineral rights. Royalties for the U.S. operations amounted to approximately $7.1 million in 2020. The phosphoric acid produced at Cajati is used to produce DCP. Canpotex sales are allocated between its members based on peaking capacity. As a result, markets for our products are highly competitive. We have a strong brand in Brazil. More than one agreement may govern our relations with each of these unions. Ben Pratt was named Senior Vice President - Government and Public Affairs in April 2020. This could adversely affect production at the Esterhazy mine. In some instances, the pandemic has impacted our business. We also use ammonia in our Brazil phosphate operations. Use of alternative means of financial assurance imposes additional expense on us. The NDC also aims to use best efforts to reduce emissions by 28%. Mosaic itself is the result of a number of industry consolidations. Any such effect could be material. The functional currency for our Brazilian subsidiaries is the Brazilian real. Item 1B.
