Gypsum is widely used in agriculture as a soil amendment and nutrient source. It helps improve soil structure by reducing compaction and enhancing water infiltration and drainage. Gypsum also helps in reclaiming sodic and saline soils by reducing sodium levels and improving the soil's ability to hold water. Additionally, gypsum provides a source of calcium and sulfur, essential nutrients for plant growth. Gypsum is used in the production of Cement and concrete. It is added to cement clinker during the grinding process to control the setting time and provide additional benefits such as improved workability, reduced cracking, and enhanced sulfate resistance. Gypsum is also used as a component in self-leveling floor screeds and in the production of lightweight concrete blocks.

Gypsum is used as a fertilizer additive and soil amendment in addition to its application in agriculture. It provides calcium and sulfur to plants and soils, promoting healthy plant growth and improving nutrient availability. Gypsum has several industrial applications. It is used in the production of Plaster molds for Metal casting, ceramic molds for pottery, and as a binding agent in the manufacture of specialized products like gypsum blocks, gypsum panels, and gypsum insulation boards.

• In Food industry:
  Plaster is used as a rich source of calcium for the body, as a filter helper in production of sugar, in beverage production to increase purity and regulate water hardness.
• In porcelain and ceramic:
  plaster also used in porcelain and ceramic industries to make a variety of molds.
• In the Glass industry:
  In the glass industry, gypsum is used to regulate the melt viscosity and also as a Substitute for sodium sulfate. 
• In the casting industry:
  Refractory plaster is used as a casting mold
• plaster in mining:
  Plaster is useful for blocking small mining tunnels.
• plaster in medicine :
  Another use of plaster will be in the healthcare industry and the production of dental plaster. There are different types of dental plaster depending on the type of application. But in any case, dental plaster must be made of a completely "pure" ore, because having some impurities after production and during application process is harmful to the mouth.
• Other uses of plaster in medicine are: 
  production of medical bandages, dental molds, bone fracture plasters, preparation of oral tablets and so on.
• In the pharmaceutical industry:
  In the pharmaceutical industry, gypsum is used as fillers and calcium-containing materials to make a variety of tablets. 
• In health products and massage service centers:
  Gypsum produce heat and open skin pores
• In the paper and Paint industry:
  Gypsum is used for paper transparency and also as a filler
• plaster in the Petrochemical industry:
  in petrochemical industry plaster act as a dryer
• The use of plaster in the leather industry:
  The use of plaster in the procurement of chemicals
• Chemical fertilizer industry:
  Application of gypsum in leather industry:
• In the preparation of chemicals:
  Such as sulfuric acid, calcium oxide, ammonium sulfate, double sodium sulfate and so on.
• Chemical fertilizer production industry:
  Sulfur fertilizer is one of the fertilizers commonly used in agriculture to improve the soil. Due to its Chemical properties, plaster is one of the raw materials used in the production of some types of chemical fertilizers.

Gypsum is utilized in the manufacturing of various plaster products apart from traditional plaster of Paris. These products include gypsum plasterboards (drywall), gypsum ceiling tiles, gypsum-based adhesives, and joint compounds. Plasterboards are widely used for interior wall and ceiling applications due to their fire resistance, sound insulation, and ease of installation. Gypsum finds extensive use in the dental industry for creating dental models and molds. Dentists use dental gypsum products to make accurate impressions of patients' teeth, which are then used for fabricating crowns, bridges, dentures, and other dental prosthetics. Sulfur deficiency is observed in soils that are highly exposed to leaching. In this case, sulfur should be added to the soil as a fertilizer.
Other gypsum applications:

• Desulfurization of waste gases
• purification of wastewater containing dyes
• Match tip
• Polishing car`s windscreens
• Toothpaste

Gypsum-based products, such as plaster of Paris, continue to be used in the medical field. Plaster casts and splints made from gypsum are used for immobilizing broken bones and facilitating their healing. Gypsum-based bandages are also employed for medical purposes, particularly in orthopedics. Gypsum is a popular material for artists and sculptors due to its workability and ability to capture fine details. It is used for creating sculptures, molds, and other artistic forms. Gypsum-based materials are also used in the field of mold-making for casting various materials, including metals, resins, and ceramics.
