FLSmidth’s filter press technology will play a central role in Rosemont Copper setting a standard for sustainable practices, including using less than half of the water as traditional mines, and reclaiming the site as permanent open space by re-vegetating throughout the life of the mine.
The large, heavy duty, 2 m x 2 m mineral-type filter presses will dewater to an optimal 16% moisture all the tailings produced from processing 68,000 metric tonnes per day of ore through the concentrator. The remaining cake can be dry stacked, which is an integral part of the progressive tailings disposal and reclamation programme being conducted by Rosemont Copper. This eliminates the need for tailings ponds and promotes ongoing reclamation and re-vegetation of the surrounding landscape.
