The pebble is reduced from the typical critical size of 38 mm x 75 mm, to approximately 12 mm and then returned by conveyor to the SAG mill feed conveyor. The screen undersize slurry reports to the primary cyclone feed pumpbox. The slurry is then pumped to a cyclopac consisting of six 813 mm diameter hydrocyclones (five operating). The cyclone underflow slurry flows by gravity to the 7.3 m x

Pebble is the by-product in sand mining. It is a kind of natural stone, which have gone through thousands years of squeezing, friction in earth movement and being carved by river. Pebble is hard in quality and has good resistant to compression, wear-resisting and anti-corrosive. It is an ideal green building material and widely used in construction and road building industry and so on.

Pebble West is relatively shallow, and would be a massive open-pit mine, almost two miles wide and a few thousand feet deep. The ore in Pebble East is much deeper beneath the surface and would be mined using block caving. This process involves mining the deposit from the bottom upwards, collapsing the ground into the cavity left behind.
