Mining Profits...Investing In Industrial Metals

Copper fell to an eight-month low in London after the U.S., the world's second-largest user of the metal, said its economy grew slower than projected in the third quarter.

Copper for delivery in three months on the London Metal Exchange declined $130, or 2 percent, to $6,400 a ton as of 2:01 p.m. local time. That's the lowest intraday price since April 21.
