The Story of Phosphogypsum

One of the byproducts of phosphate fertilizer production is phosphogypsum – a damp gypsum powder that is typically stored in large stacks next to where the fertilizer is manufactured.

Agrium has active ‘gypstacks’ at our Redwater fertilizer plant near Edmonton, Alberta and our Conda Phosphate Operation near Soda Springs, Idaho – as well as an inactive one near our Fort Saskatchewan site in Alberta. But you may have driven past these large human-made hills without even knowing it, as they exist all over the world.

Occasionally, we get questions about our gypstacks, so we’ve put together a video to provide some information about the origins, characteristics and potential uses of phosphogypsum. Please feel free to watch – and visit our YouTube Channel for more great videos.
