Alarming Impacts of gypsum mining on Ecosystems and Water Resources. Gypsum mining, predominantly carried out for its use in the construction industry, has its own set of environmental challenges. Gypsum extraction through open-cast mining can lead to habitat fragmentation, biodiversity loss, and altered soil composition.
America is blessed with abundant low-cost natural gypsum. There is also an abundance of flue gas desulfurization gypsum produced as a by-product of coal-fired power plants. As a result, the market for the phosphogypsum generated by the chemical processing of phosphate rock has traditionally been limited.
from flue gas desulphurisation; a process for cleaning up emissions from chimneys to reduce the quantity of sulphurous gases flowing into the atmosphere. Dehydration: Rock into plaster Gypsum rock is converted into gypsum plaster by driving off some of the chemically combined water. Heating gypsum at 120°C for one hour results in a hemi …
