Sedimentary phosphate ore mined and beneficiated to marketable grade (28–35% P₂O₅). The irreplaceable source of phosphorus for all phosphate fertilizers (MAP, DAP, TSP, SSP). Phosphorus cannot be synthesized or substituted — it must come from mined rock. Morocco + Western Sahara control ~70% of global reserves; China controls ~43% of current production.

Who makes it
6 companies produce phosphate rock (fluorapatite ore).
World's largest phosphate company; controls ~70% of global proven phosphate rock reserves and 31% of world phosphate product market. Morocco's phosphate deposits (Khouribga, Gantour, Bou Craa) are the largest in the world. OCP controls 54% of global phosphoric acid trade and 26% of phosphate fertilizer market. Single-entity concentration of a resource essential for all animal and crop nutrition makes OCP a strategic geopolitical chokepoint.
World's largest phosphate rock producer and exporter; also largest single consumer of sulfuric acid globally. Consumed 11.3M MT H2SO4 in 2023 — equivalent to all of Germany's sulfuric acid output — to produce phosphate fertilizer at Jorf Lasfar complex. In January 2025 announced $1.2B investment to expand H2SO4 and fertilizer capacity. Produces H2SO4 on-site by burning imported elemental sulfur (shipped from Middle East producers and refineries). Morocco holds ~70% of global phosphate reserves.
Russia's largest phosphate producer and one of the world's largest fertilizer companies. Operates the Apatit subsidiary at the Khibiny deposit (Kola Peninsula, Murmansk region) — one of the world's largest and highest-grade phosphate deposits (P2O5 content ≥37.5%). Khibiny is Russia's ONLY apatite-nepheline ore source. New +10m level of Kirovsky mine commenced March 2024. NOT under Western commodity sanctions (unlike Belaruskali/Uralchem in fertilizers). Russia produced 14M MT phosphate in 2024. PhosAgro simultaneously produces nepheline concentrate from the same Khibiny ore — a byproduct used in aluminum and glass manufacturing.
Saudi Arabia's state mining company. At Wa'ad Al Shamal, operates integrated H2SO4 production using elemental sulfur from Saudi Aramco as feedstock — advantaged access to low-cost domestic sulfur. H2SO4 produced on-site is consumed entirely within the integrated phosphate fertilizer process. Ma'aden is both a major H2SO4 producer and consumer at a single integrated complex. Bought out Mosaic's 25% JV stake Dec 2024.
World's largest US potash and phosphate producer. Esterhazy K1 and K2 mines (Saskatchewan) began experiencing managed brine inflows in 1985; managed for decades until Mosaic made the decisive choice to build the K3 underground mine (announced 2009, commissioned 2022) to replace K1/K2. K1/K2 closed 2021. K3 at Esterhazy is now the world's largest operating potash mine. Also operates Colonsay SK mine (conventional underground). The Esterhazy flooding saga represents the most consequential water-management incident in Saskatchewan potash history, requiring a $4B+ replacement mine investment.
World's largest potash producer with 6 Saskatchewan mines. Vanscoy mine (west of Saskatoon) uses solution mining technology — fresh water drawn from the Saskatchewan River (~20km pipeline) is used in brine management. Deep subsurface saline aquifer brine injection used for waste disposal at Vanscoy (injected into Winnipeg/Deadwood Formations at 1,500-1,700m depth). Conventional underground mines at Rocanville, Allan, Lanigan, Cory, Belle Plaine also produce waste brine requiring aquifer disposal. Nutrien operates Canada's only solution potash mine at Vanscoy. Plans to reach 18M MT/year Saskatchewan capacity.
