At some gypsum plants, drying, grinding, and calcining are performed in heated impact mills. In these mills hot gas contacts gypsum as it is ground. The gas dries and calcines the ore and then conveys the stucco to a product cyclone for collection. The use of heated impact mills eliminates the need for rotary dryers, calciners, and roller mills.

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.

Gypsum waste can be turned into recycled gypsum by processing the gypsum waste in such a way that the contaminants are removed and the paper facing of the plasterboard is separated from the gypsum core through mechanical processes including grinding and sieving in specialised equipment. Gypsum waste such as gypsum blocks and plaster do not require the removal of paper, as they are not made

Primarily, gypsum is used for helping to break up heavily compacted clay soils making them more porous and able to absorb moisture. This is particularly helpful in areas prone to drought. The addition of gypsum can promote better drainage and air circulation, which can aid root development and nutrient absorption.
