Mechanism of water extraction from gypsum rock by

2020-5-19  Microorganisms attach and form biofilms on the {011} planes of gypsum crystals; gypsum dissolves, and water extraction occurs. Based on the crystal structure of gypsum, the water of crystallization layer is exposed to the {011} planes, but not to the {010} planes.

2018-8-15  The previous study showed that dry gypsum could enrich mercury from air, while wet gypsum could release mercury into the environment . Once the mercury is leached from gypsum, it can react with sulfite and other reducing substances in the environment and be transformed into Hg 0, then released into atmosphere . It is well known that both physical adsorption through weak binding force and chemical adsorption can result in the enrichment of Hg in FGD gypsum.
