Considerable losses are expected for Thailand. After 5.5 Mta natural gypsum exports in 2019, a maximum of 3.5 Mta are expected by 2030. Germany will also reduce its export rates, too, as less FGD gypsum is available for domestic industry and this must be offset to an extent by more natural gypsum. 3 FGD gypsum and other synthetic gypsum

Flue gas desulfurization (FGD) is a very common method for gas claning adopted in a gas processing plant. In this process, the flue gas with acid vapors is scrubbed to remove it as a by-product. Most of the FGD processes use alkali to scrub the flue gas. Many designers of FGD adopt the limestone gypsum process.

The flue gas desulfurization (FGD) processes can be separated into two main categories: once-through and regenerable processes, depending on how the sorbent is treated after SO 2 adsorption (Srivastava and Jozewicz, 2001).Once-through, or non-regenerable, processes utilize the sorbent as a beneficial by-product or dispose of it as …
Mineral Processing. Gypsum processing can be divided into three basic steps: (1) rock preparation, (2) calcining, and (3) formulating and manufacturing. This is illustrated graphically with the flow chart in Figure 1. The specifics of each step will vary with the quality of the gypsum and with the type of final product.

Gypsum Mining Process Gypsum processing equipment differs significantly in scale and level of technology. some plants produce one or two tonnes per day using low-cost manual technologies, some other plants of a thousand tonnes per day that are …
Even the best lithium ores only contain 3 - 6% lithium by mass, leaving 94 - 97% currently unused. As electric mobility grows, by-product gypsum from the lithium sector could partly offset the expected fall in flue-gas desulphurisation (FGD) gypsum supplies. Iryna Yermakova introduced the Etex Group's approach to the wallboard plant of the future.
