Copper-bearing rock (ore) is blasted underground, scooped up by front-end loaders, taken in large trucks to underground crushers, then hoisted to the surface in skips up one of the shafts. At the surface, the ore is crushed further, mixed with water and other special chemicals to remove the waste rock and float the copper ore so it can be skimmed off, then heated and treated in other ways to purify the copper and separate it from any other metals.
Most of America's copper mines are open pit mines, huge digs into the ground using massive trucks and cranes to move the covering dirt and haul the ore off to be processed.
Miners first had to sink a shaft beside a deposit of copper. From the shaft, men dug tunnels out at different levels. the the ore (copper and dirt) is loaded into a big tonka truck. the truck then takes the ore to a crusher (what it does is self explanatory) the crushed ore called sluge is take to the refinerary. where it is melted down and formed in to shapes.
