National Gypsum to close Shoals mine late this summer

with 2 comments

This is big news for the town of Shoals, Indiana, home to two gypsum plants:

National Gypsum, the second largest gypsum producer in the US, which runs the biggest gypsum mine in the world, will stop mining activities at Shoals mine in Indiana, where the plant will produce synthetic gypsum from flue gas desulphurisation FGD.
via National Gypsum will close one gypsum mine in the US | Industrial Minerals.

The plant will be adapted to use the synthetic gypsum, which is purer than mined gypsum, at a cost of around $15 million. The changeover will affect 21 miners.

(In case you’re curious, the “biggest gypsum mine in the world” is a quarry in Nova Scotia, which supplies rock for National Gypsum‘s East Coast plants.)

Geologists have noted the existence of gypsum in Southern Indiana since at least 1922. But it wasn’t until the 1950s that it was determined there was a substantial deposit of gypsum in Shoals worth mining. The front page of The Shoals News dated December 26, 1952, announced the news:

Today I discovered a wonderful slide show of the US Gypsum mine and board plant in Shoals, Indiana. The photos date from 1978 — check out that Farrah Fawcett poster in the mine lounge! If you look at the photos individually, there are notes explaining the context.

I was still attending Shoals High School in 1978. Every year USG graciously hosted the local eighth grade class for a tour of the board plant, introducing them to the town’s largest industry.
