Potash (Muriate of Potash / KCl)

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.

Russia's largest potash producer; ~17% of global supply. Five mines and seven ore-treatment mills in Berezniki and Solikamsk (Perm Krai). NOT under Western sanctions (unlike Belaruskali) — continues to export to China, India, Brazil, Indonesia, Turkey, and the EU despite Russia-Ukraine war. Controlled by oligarch Dmitry Mazepin (under personal sanctions). Berezniki mines produce ~10% of world's potash but the city is being swallowed by sinkholes from 2006 mine flooding — a structural geological risk. Russian potash exports rose 30%+ in 2024 reaching ~10M MT.

State-owned Belarusian potash company; historically ~18-20% of global MOP supply. Soligorsk mines have the world's highest-grade potash ore. Subject to US and EU sanctions since 2021 following disputed election and Lukashenko repression. Lost access to Klaipėda (Lithuania) port in February 2022 — the only viable Baltic export route — causing production to fall 60% in 2022 (to 3M MT). Has rerouted exports through Russian ports (Ust-Luga, Murmansk). Recovering to ~7M MT by 2024. Belarus and Russia jointly produce ~40% of global potash exports.

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.

Israeli specialty mineral company; ~25% of global food phosphate market per input description; 15-18% of total global STPP market. ICL Food Specialties (subsidiary) is a leading food phosphate supplier: STPP, SHMP, SAPP, and other sodium phosphates for water binding, texture, and moisture retention in processed meat. Also: world's largest bromine producer (Dead Sea), potash producer (Dead Sea Works), and specialty fertilizer company. ICL has a unique triple position in critical minerals: food phosphates, potash fertilizers, and bromine for flame retardants/pharmaceuticals. Lawrence, KS plant serves the North American processed meat industry.

German potash and salt producer; operates mines in Germany (Werra, Weser, Harz) and Canada (Bethune mine, Saskatchewan); ~7% of global potash; only Western European potash producer; operates under EU environmental constraints; Bethune mine opened 2017 as first new greenfield potash mine in Canada in decades
