Formation of α-Hemihydrate Inside of a Gypsum Crystal …
Gypsum (calcium sulfate dihydrate) is one of the most used inorganic binding materials in the world. During calcination, calcium sulfate subhydrates are formed and, for technical reasons, are mixed with water to form dihydrate again. Therefore, the dehydration process of gypsum and the rehydration of hemihydrate were investigated. This …

Making Gypsum Board
ASTM standards govern the manufacture of gypsum board and set strict criteria for strength, water resistance, and other characteristics. To produce gypsum board, crushed natural gypsum or synthetic gypsum is heated or calcined to dehydrate the feedstock. Next the calcined gypsum is mixed with water and additives to form a slurry which is fed

Separation of Gypsum by the Flotation Process
Especially, from the views of separation and recovery of gypsum, the following treatment would be recommended which the concentrates risen by flotation were well washed by water, because of the greater solubility of such coexisting salts as NaCl, MgSO 4, MgCl 2 and so on than that of gypsum in water.

Calcining processes for natural and synthetic gypsum
The hammer mill, being a short-time calcining system, grinds, dries, calcines and classifies the raw gypsum in a single step. The resulting stucco is suitable for the production of plasterboard, gypsum fiberboard and gypsum wall blocks. A hammer mill can process moist FGD gypsum, pre-crushed natural gypsum, or a mixture of both.

Potash Flotation Process
Potash Flotation. The conditioner and reagentized salt-brine slurry is floated in a "Sub-A" Flotation Machine. In the circuit shown, roughing is accomplished in a "Sub-A" Free Flow Flotation Machine with no intermediate s or feed pipes. This allows the coarse sodium chloride waste product to flow through the machine unmolested.

Utilisation of FGD gypsum for silicate removal from scheelite flotation
The gypsum produced from flue gas desulphurisation (FGD) can dissolve in the solution and release calcium ions. FGD gypsum also has an adsorption ability for heavy metal ions [15], thus, it maybe is a feasible choice for wastewater treatment. FGD gypsum is produced from the process of wet limestone flue gas desulfurization.

Flotation purification of waste high-silica phosphogypsum
The main impurity mineral in the raw PG was quartz. Flotation is an effective method to separate quartz and gypsum, but the quartz needs to be effectively inhibited in the flotation process (Xiao et al., 2022; Zhang et al., 2022). The desilication flotation tests were implemented with the slurry pH in the range of 2–2.5.
