A global landmark in mining has been achieved at the Boulby mine.

During operations on Wednesday (Sept. 13th) the one-millionth tonne of polyhalite was brought to the surface.

Mark Elliott, Polyhalite Production Manager, was quick to praise everybody for working together to make the goal achievable: “Every man jack in every department has had a part to play in this success,” he said. “Since we started to focus on mining polyhalite in early 2016 everybody has worked to find ways of improving productivity. Output has increased to 327,000 tonnes so far this year and we are on target to hoist 450,000 by the year end.”

Of particular note was the contribution made by the engineers to the cutting heads. Polyhalite is so hard that at first some 100 of them had to be replaced per shift. A redesign has reduced that to between fifteen and twenty, saving time and enabling each shift to mine more of the mineral.

As you all probably know, we are the only mine in the world producing the mineral which we market under the trademark ‘Polysulphate’.

And the increase in productivity is also helping meet the increasing worldwide demand for the product which, because it occurs naturally, is approved for use in organic farming systems that are becoming increasingly popular.
