Its processing value is very high. The use of a professional desulfurization gypsum production line can enhance the application value of the by-product desulfurization gypsum. Among them, limestone-gypsum wet method is used. The desulfurization process is technically mature and widely used. Only limestone wet desulfurization gypsum is easy to use.

In the early days of gypsum mining, farmers drove their horses and wagons as far as 100 miles to purchase supplies of "land plaster" for use as fertilizer, or soil "sweetener" as it was called at the time. The primary use of gypsum through this period was as land plaster and fertilizer until about 1880.

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.
