A new building which will boost the production of polyhalite at Cleveland Potash has been given the go-ahead by councillors.
Located within the existing Boulby site, the crushing and screening plant will house a dedicated facility for processing the fertiliser mineral.
The structure will cover an area of 98 metres by 31 metres wide, with a maximum height of 34 metres.
It will include new conveyors, elevators and equipment, which will convert the polyhalite ore into a new product range.
North York Moors National Park Authority’s director of planning, Chris France, said: “In order to develop this production line it is accepted that a new facility within the development is needed.”
It is hoped the new facility, which will have the capacity to hold 12,000 tons of extracted material, will help secure the long term future of the business and its employees.
Cleveland Potash is currently the world’s only miner of polyhalite.
Earlier this year, the company was awarded £4.9 million from the Government’s Regional Growth Fund to support a £38 million project focussed on mining and processing polyhalite, a move that could create 125 jobs.
Studies by the firm show up to a billion tonnes of polyhalite sit below the Yorkshire coastline.
Rival firm Sirius Minerals intends to focus on mining polyhalite if plans to build a multi-million pound potash mine on the outskirts of Whitby are approved.
