Summary:
Nutrien extract phosphate ore using surface mining techniques. At each minesite, the ore is mixed with recycled water to form a slurry, which is pumped from the mine site to processing facilities.
Because the ore lies about 120 feet below the surface, mining occurs in two stages:
-First, about 45 feet of sand and clay, called overburden, is removed.
-Then, the three draglines dig the remaining 80 feet of overburden so they can mine the ore below.
