The Role of Drying in Gypsum Mineral Processing. After gypsum ore is extracted from mines or quarries, it is crushed and stockpiled as needed. If the gypsum ore's moisture content is greater than 0.5 weight percent, then the material requires drying. A gypsum dryer is commonly used to reduce the moisture content of the ore to the necessary level.

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.
