Gypsum Processing for Wallboard

Gypsum Processing for Wallboard. Gypsum is a soft sulfate mineral composed of calcium sulfate dehydrate, with the chemical formula CaSO₄·2H₂O. It is widely used in a variety of appliions and is the main ingredient in many forms of wallboard, block, and plaster products.

ASTM International - Byproduct Gypsum

Byproduct gypsum is the chemical end product of industrial processing plants, consisting primarily of calcium sulfate dihydrate, CaSO 4 ·2H 2 O. The oldest byproduct-gypsum-producing industry is that of the phosphate rock chemical processing in Florida.

Production of low-fluorine gypsum as a by-product in a

The gypsum is filtered a second time on the rotary filter and is then calcined for the purposes of further processing by the cement-sulphuric acid process. Its fluorine content of 0.15% based on the anhydrite is in accord with the requirements.

Properties and Uses of Gypsum - Science Struck

Gypsum is made up of oxygen, calcium, sulfur, and water, and its chemical formula is CaSO 4 ·2H 2 O. Gypsum beds were formed due to the evaporation of water from the massive prehistoric sea basins. When water evaporates, the minerals present in it become concentrated, and crystallize.

FGD Gypsum Introduction

FGD Gypsum is a unique synthetic product derived from flue gas desulfurization (FGD) systems at electric power plants. Sulfur dioxide emission control systems used by coal-fired power plants remove sulfur from coustion gases using "scrubbers."

Solubility and Solubility Product of Gypsum in Soil

The solubility of CaSO 4 ·2H 2 O in several soils and dilute aqueous electrolytic media was measured. The ionic strength of electrolytic media ranged from 0.059 to 0.314; the solubility product of gypsum in these solutions ranged from 2.13 × 10 ‐5 to 2.79 × .10 ‐5 with an average value of 2.51 × 10 ‐5..

Gypsum Products - CECO Environmental

In Gypsum Product Manufacturing, the chemical composition of gypsum is calcium sulfate dihydrate (CaSO4·2H2O). There are two types: natural gypsum and Flue-Gas Desulfurization (FGD) gypsum. FGD gypsum is a by-product of desulfurization of flue gas from the stacks of fossil-fueled power plants.
