To protect our valuable water resources and the environment, Sandfire has designed a Cemented Tailings Facility (CTF) that improves on established practices by allowing for a solid, dust free facility. After filtering and squeezing out most of the water, tailings mixed with cement will be permanently stored in a 100 mil High Density Polyethylene (HDPE) double lined facility in a non-flowable state. There will be a pump back system placed in the bottom of the facility so that the small amount of water squeezed from the tailings as it sets up as well as any precipitation occurring on the facility is pumped from a sump into a double lined process water pond.
