What are gypsum mines used for? - Daily Justnow

Gypsum is a soft sulfate mineral composed of calcium sulfate dihydrate, with the chemical formula CaSO 4·2H2O. It is widely mined and is used as a fertilizer and as the main constituent in many forms of plaster, blackboard/sidewalk chalk, and drywall. How do they mine gypsum? It is liberated from its natural state most commonly by surface mining.

Rainbow Rare Earths, RBW, - Could The Plan Actually Work?

If it could be cleaned up then it could become gypsum for plasterboard (sheetrock to Americans). And cleaning it up would have the effect of extracting the rare earths as well. Or, the other way around, extracting the rare earths would clean up the gypsum. This could work - technically definitely it works - it's a matter of economics.
