It was one of the richest ore deposits ever discovered and produced over $100,000,000 in profit! When they decided to shut the mine down, the miners were given 24 hours notice to gather what they could carry and be on the last train out of town.

Kennicott Mine & Ghost Town Walking Tour

This abandoned copper mining camp is a National Historic Landmark District. Established in 1903, Kennecott Mining Corporation operated 5 mines in the area. Kennecott became a bustling mining camp filled with miners and their families. In 1925, a geologist predicted that the area would soon be mined out. By 1938, Kennecott was a ghost town.

Blue Patina on Copper: 5 Steps (with Pictures)

Sides of the table are also separate 16 guage copper strips laminated to the sides. Patination for all the pieces was 2 stages done in a large airtight plastic tub. First stage ammonia fume only, then a rinse to remove the non-adherent bits, then a second round with vinegar + salt in addition to the ammonia fume.

Treatment of Mixed Sulfide Oxide Ores of Copper

During the past five years, ammonia has been used successfully in the treatment of ores quite outside the range of any acid solvent. At the Calumet and Hecla mine, ammonia is used to dissolve native copper; at the Kennecott, it is used to dissolve oxidized copper minerals. At both places the ore is so high in calcite that an acid could not be used.

ATSDR - Public Health Statement: Copper

 · Copper is a reddish metal that occurs naturally in rock, soil, water, sediment, and, at low levels, air. Its average concentration in the earth's crust is about 50 parts copper per million parts soil (ppm) or, stated another way, 50 grams of copper per 1,000,000 grams of soil (1.8 ounces or 0.11 pounds of copper per 2,200 pounds of soil).

Tighter regulations: What miners need to know about MDMER ...

 · The maximum monthly mean concentration for copper is reduced from 0.3 to 0.1 mg/L. Copper is fairly easy to remove at high pH with a coagulant provided it is not complexed with ammonia or some other substance, and with the new ammonia requirements it is unlikely that enough ammonia will be present to cause issues.
