Gypsum (CaSO4·2H2O) is the most common sulfate mineral on Earth and is also found on Mars. It is an evaporitic mineral that predominantly precipitates from brines. In addition to its precipitation in natural environments, gypsum also forms an undesired scale in many industrial processes that utilize or produce brines. Thus, better insights into …

For clay soils, a general application rate is about 40 to 50 pounds of gypsum per 1,000 square feet. Again, it's important to conduct a soil test for more accurate recommendations. How much gypsum do I add per acre? A rough estimate is to apply 1 to 2 tons (2,000 to 4,000 pounds) of gypsum per acre for soil amendment.

Status of phosphogypsum utilization. Natural gypsum (CaSO 4 ·2H 2 O) is a versatile industrial and construction material, which is heavily mined and this resource is being depleted as it is non-renewable. Since the physicochemical and mechanical properties of PG are similar to those of natural gypsum (Moalla et al. 2018), it has …

When gypsum is heated at about 150–160 °C, it loses approximately three-quarters of its water in a partial dehydration process and becomes hemihydrate gypsum (CaSO 4 •½H 2 O) or calcined gypsum; it is also known as beta gypsum (alpha gypsum is made by processing batches of gypsum under elevated pressure). Calcined gypsum or …

Gypsum ore is dug out from quarries and mines. It is crushed and stored close to the plant. As per the requirement, the stored ore is further ground and screened to approximately a size of 2 inches or 50 mm diameter. In case the mined ore has a high moisture content (more than 0.5% of weight), it is sent to a rotary dryer for further drying.
