Sulfuric acid from gypsum I have made the following research: 2 CaSO4 + 2 SiO2 + C → 2 CaSiO3 + 2 SO2 + CO2 SO2 + O2 (V2O5@400-600C) → SO3 SO3 + H2O → H2SO4 This dictates that 2720 grams of calcium sulfate would generate 1960 grams of 100% sulfuric acid by theory. The idea is that the gypsum is roasted with sand and coke at high temperatures.

The mixing of sulfuric acid and phosphate creates gypsum (called phosphogypsum) as a byproduct. Although gypsum can be used for a variety of purposes, the EPA prevents usage of Florida's phosphogypsum because it retains low levels of radioactivity found in the host sediments. At present, phosphogypsum is piled up around the processing plant.
