Surface mining technology minimizing blasting concerns. First, drilling and blasting fracture the exposed gypsum. The fractured gypsum is then transported to a processing plant where larger units are reduced in size by a crusher. This generates a mixture of smaller rocks that are then cleaned and sorted by size.
The estimated raw mineral production value at the lip of the mine is in excess of 483 million annually. South Carolina minerals are surfacemined. Surface mining involves the removal of unwanted rock and soil prior to the extraction of the mineral.
