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.

The pyrite reactor supported the SNAD process with a maximum nitrogen removal efficiency of 139.5 mg/(L⸱d) when the DO concentration was in the range of 0.8–1.5 mg/L. This range, however, limited the denitrification efficiency of the reactor, which decreased from 90.0% ± 5.3% in phases II–V to 67.9% ± 7.2% in phases VI and VII.

A novel process is described to recover elemental sulfur, high-grade calcium carbonate and a concentrate of rare earths. The process entails carbo-thermal reduction of gypsum to form calcium sulfide using ordinary bituminous coal as both energy and carbon source, followed by extraction of calcium sulfide as an aqueous solution of calcium bisulfide. …
