Gold Futures Plunged $10

Gold futures plunged in crude oil to a three-month low added to signs of weakening global economic growth.

Platinum headed for its biggest three-day drop since at least 1992 as exports of vehicles from China slowed in the first-half, capping demand for emission-control car parts, the metal's biggest market. Gold has dropped 8 percent since July 11, when oil began its 20 percent slide from a record high.

Gold for immediate delivery dropped $9.75, or 1.1 percent, to $885.05 an ounce as of 10 a.m. in London after earlier declining to $882.16, the lowest since June 25.
