In the United States, crude, synthetic, and calcined gypsum production amounted to 20.0, 16.0, and 17.0 million tons respectively (Crangle, 2021). Gypsum is a very cheap material, so, to increase economic efficiency, the use of spent sulfuric acid as a source of sulfuric acid can be also proposed.
All amendments were effective in crusting prevention and soil reclamation, but sulfuric acid was the most efficient due to the fastest EC and Na reductions in the leachates. Sulfuric acid and gypsum-like by-products are potentially effective amendments in preventing soil crusting and reclaiming calcareous sodic soils. However, their relative efficiencies at …
The papers in this issue focus on sulfuric acid. Sulfuric acid has become an integral part of the mining industry and today there are more sulfuric acid plants operated in the mining industry than in the chemical industry in South Africa. This revolution took place in the 1950s with the advent of the uranium extraction and recovery process.
