Boron, California Operations U.S. Borax

Ore from the mine must be crushed before it can be refined. Powerful crusher machines reduce the ore to 1-inch (2.5 cm) pieces, increasing the ore's surface area to make the refining process more efficient. Ore is transported out of the mine and throughout the refinery via an extensive system of conveyors.
