Calcium carbonate

The resulting calcium sulfite collects at the base of the absorber and compressed air is blown into this residue. The calcium sulfite reacts with the air to form calcium sulfate (gypsum), used to make, for example, plaster board and cement. Very fine and pure calcium carbonate is used as filler in

Caves, Canyons, Cactus Critters

As the hydrogen sulfide was oxidized deeper and deeper in the cracks, the deep pits of the caves formed. When groundwater levels changed, the passages formed at new levels. One byproduct of the reaction of sulfuric acid and limestone (primarily calcium carbonate) was calcium sulfate, or gypsum, which was subsequently deposited in the great voids.

Phosphoric Acid

Phosphoric acid is produced from fluorapatite, known as phosphate rock, 3Ca 3 (PO 4) 2.CaF 2, by the addition of concentrated (93%) sulfuric acid in a series of well-stirred reactors. This results in phosphoric acid and calcium sulfate (gypsum) plus other insoluble impurities.

High Soil pH

Once the sulfuric acid is formed, it will react with the calcium carbonate in the soil. If there is enough elemental sulfur to form sulfuric acid and react with all of the carbonate in the soil, the soil pH will continue to decrease over time and stay at the lower pH value in the future. In the two years since the elemental sulfur was applied
