Commodities prices are ending broadly lower as weakness in corporate earnings reports dims the outlook for the U.S. economy.

The government reported a slight pickup in U.S. economic growth for the third quarter Friday, to 2 percent from 1.3 percent in the second quarter, but that's still not fast enough to make a dent in the unemployment rate, which currently stands at 7.8 percent.

Metals prices ended lower, continuing a weeklong slide. Platinum and palladium fell about 1.5 percent, while gold, silver and copper had smaller declines.

Gold fell $1.10 to settle at $1,711.90 an ounce.

Grains and bean fell. Energy prices edged higher.
