“Pursuant to the amended Sulfuric Acid Supply Agreement, Itafos will continue to purchase sulfuric acid from the Kennecott mine in Utah.” — source, 2026-11-13
The May 2026 release shows smelter acid from Utah supplying about 60 % of the acid needs of the Conda phosphate plant, under a contract whose reference index was changed in 2026 because of sulfur volatility. It is a route to phosphoric acid that does not pass through elemental sulfur bought at Tampa terms. Inferred: such acid is worth more when sulfur is scarce; the release gives no price.
