Kennecott, also known as Kennicott and Kennecott Mines, is an abandoned mining camp in the Valdez-Cordova Census Area in the U.S. state of Alaska that was the center of activity for several copper mines. It is located beside the Kennicott Glacier, northeast of Valdez, inside Wrangell-St. Elias National Park and Preserve.The camp and mines are now a National Historic Landmark District ...

With the exception of some iron ore tailings, it is probable that most mill tailings will be very fine-grained materials with 50 percent or more of the particles passing a 0.075 mm (No. 200) sieve. Other physical properties of mill tailings include specific gravity, unit weight, and moisture content.

Mill tailings were disposed of in an area below the mill. The concentrated ore and the direct shipping high-grade ore were loaded into bags for shipment by rail. In 1916 an innovative ammonia leaching plant was constructed to further recover the copper oxides from the tailings. In 1925, flotation was introduced to boost total recovery to 96%.

What doesn't float is called tailings because it goes out the "tail end" of the flotation circuit. About 80 percent of the water used in the milling process is reclaimed and re-used. The rest is used to keep the tailings damp and to prevent wind-blown dust.
