The world's only producer of
We are the first and only
polyhalite producer globally
ICL Boulby Mine is an underground mining operation and processing facility located along the North Yorkshire coastline.
The 260-million-year-old raw mineral, polyhalite, is extracted from 1,300 meters beneath the Earth’s surface and distributed worldwide from our Teesdock Terminal.
Our Polysulphate is proudly produced in Britain and sold in 22 countries across five continents.
ICL PotashpluS™
polyhalite producer globally
Polyhalite was formed approximately 260 million years ago during the Permian era, when Europe was located much further south. At that time, Boulby was positioned at the edge of a vast, shallow ocean known as the Zechstein Sea. The hot and arid conditions of the era caused the water to evaporate faster than it could be replenished, resulting in the deposition of polyhalite and halite minerals that we now extract.

Polysulphate is a multi-nutient fertiliser and is is produced from a natural mineral called polyhalite, which is an evaporite mineral containing sulphur, potassium, calcium and magnesium.
Boulby mine is between 1,100 and 1,400 meters deep, making it the deepest mine in the UK.
As well as polyhalite, rock salt is extracted to be used in animal feed and to de-ice the roads of Great Britain.
Boulby Underground Laboratory is the UK’s deep underground science facility located 1.1km below ground. Run by STFC (Science and Technology Facilities Council) the science ranges from Particle Physics and Ultra-Low Background science, Earth and Environmental science, Biology / Astrobiology, Planetary Exploration Technology Development and more.
