impact of mining gypsum
The Environmental Impact of Spodumene Mining
The spodumene moves to a dryer and kiln that operate at about 1,000°C. This process converts the mineral into an easy-to-extract form using acid. This stage in the process also has the potential to release chemicals in the environment, some of which can be attributed to the fuel quality, calciner design, and emission abatement steps.

Mined gypsum contains both quartz and dolomite [CaMg(CO₃)₂]. FGD gypsum usually possesses a much smaller and more uniform particle size (more than 95% < 150 microns) than agricultural mined gypsum that is granulated to produce a final size of 2–4 mm. However, FGD gypsum can also be processed to form larger-sized granules.

Gypsum Plasterboard and the environment
Calcium Sulphate Dihydrate (Gypsum) is commonly hydrated by groundwater. The UK is largely self-sufficient in gypsum. The material can be found in seams in the Pennines and the Midlands, but the biggest source of extraction is in East Sussex where mining extracts some 100,000 tonnes of gypsum a year from 100 m below the High Weald.
