ROM ore from the open pit is crushed in a gyratory crusher to 80% minus 150mm, followed by screening on a double deck vibrating screen for pebble generation. The screen oversize and undersize is recombined and conveyed to the mill feed stockpile. Mid-size material is used as grinding media in the pebble mill, and is conveyed to a storage bin.

And yet, the threat of Pebble remains. Members of Congress must investigate the Pebble Limited Partnership for their fraudulent mine plan and lies to the American people and federal regulators, and urge the Army Corps to deny Pebble's permit today- and they must act
