Sibelco UK Ltd


Sibelco is the world’s largest producer of hydraulic fracturing sands, through its subsidiary Unimin Energy Solutions in the US, and also currently produces UNIFRAC® Hydraulic Fracturing Sands in four European countries (Belgium, France, Russia and UK). Sibelco supplied Cuadrilla Resources (PDF) with frac sand for its ill-fated Preese Hall‐1 well in from quarries in Cheshire and seems likely to continue to do so.
