| Obtained by removing impurities from natural gypsum ore and heating the soil on an electric furnace to 300 ℃ for calcination and grinding. Sodium sulfate is added to calcium chloride, a byproduct of the ammonia alkali method, and the product is refined. Byproducts during the production of organic acids. For example, calcium oxalate obtained during the production of oxalic acid is refined by decomposing it with sulfuric acid. | |||||||||
