Berkeley Pit
The Berkeley Pit is a former open pit copper mine in the western United States, located in Butte, Montana. It is long by wide, with an approximate depth of . It is filled to a depth of about with water that is heavily acidic (2.5 pH level), about the acidity of Coca-Cola, lemon juice,Edwin Dobb. "New Life in a Death Trap". ''Discover'', 2000. or gastric acid. As a result, the pit is laden with heavy metals and dangerous chemicals that leach from the rock, including copper, arsenic, cadmium, zinc, and sulfuric acid. The mine was opened in 1955 and operated by the Anaconda Copper Mining Company, and later by the Atlantic Richfield Company (ARCO), until its closure on Earth Day in 1982. When the pit was closed, the water pumps in the nearby Kelley Mine, below the surface, were turned off, and groundwater from the surrounding aquifers began to slowly fill the Berkeley Pit, rising at about the rate of per month. Since its closure, the water level in the pit has risen to withi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Triketones
In organic chemistry, a triketone or trione is an organic compound containing three ketone () groups. The simplest triketones, such as cyclopropanetrione and 2,3,4-pentanetrione, are only of occasional theoretical interest. More pertinent are triacetylmethane and 2,4,6-heptanetrione. Both species exist predominantly in the enol () forms.
