Results show that there are no harmful impacts on the environment of the studied area associated with the extraction and quarrying of the gypsum deposits at the Maqna area. They also revealed that the gypsum can be quarried using a ripping technique, which does not create noise and/or vibration in the surrounding areas.

The mining of gypsum also has the potential to affect the lake's fringing vegetation. Therefore, if the proposal is approved, conditions need to be imposed to ensure that impacts do not significantly affect the lake's waterbird habitat values. This applies particularly to the migratory species which use the lake. Local species are likely

Taking a typical wet FGD unit of 300 MW power plant in China as an example, the limestone/gypsum flue gas desulfurization system (L-FGD) process was compared with the LCS by using the method of life cycle assessment and life cycle cost (LCC). The result shows that the overall environmental impact of the LCS is 0.2913.

The impact of mining is leading to the major issues, like a threat to the entire environment and also damaging the health of all life on Earth. Mining procedures generally require a larger and vast area of land. Deforestation is a by-product of mining and the build up of the mining areas requires constructing roads and residences for the mine employees and often vegetation farms are abolished.
