“Sulfuric acid production from our smelters in the U.S., Spain and Indonesia, together with our sulfur burner plant at the Safford mine, generally exceeds the requirements of our SX/EW leaching operations.” — source, 2026-11-13
The 10-Q shows a domestic sulfur burner at Safford, Arizona, and smelter acid that exceeds the company's own leaching needs, and states that acid price swings are not material to its results. Inferred: it buys some sulfur in the same market and sells surplus acid into a short one, so effects partly offset. Not shown: sulfur purchases or acid sales to fertilizer makers.
