CHICAGO, May 12 (Xinhua) -- Gold futures on the COMEX Division of the New York Mercantile Exchange ended higher on Tuesday due to a weak dollar and worries on potential inflation as the economy is recovering. Silver and platinum went up, too.

    Gold price for June delivery gained 10.40 U.S. dollars, or 1.1 percent, to settle at 923.90 dollars an ounce.

    A weak dollar is considered the main factor which helped the precious metal climb. The rate against euro touched 6-week low earlier in the session, giving much support to gold's gain. Generally speaking, the precious metal is used as a hedge against dollar's depreciation.

    Crude oil's rally also provided a strong base tone to gold, despite the fact that it retreated from the 5-month high of 60.08 dollars a barrel on Tuesday morning.

    Oil prices have been rising in recent weeks on the hope that energy demand will soon pick up as the economy shows some early signs of improvement. The climbing energy price as well as more and more evidences indicating the world economy is on the way to recover from the most serious recession since the 1930s, made investors keep an eye on the potential inflation, which strengthened gold's appeal of safe-haven.

    July silver finished at 14.215 dollars per ounce, up 30.5 cents. July platinum rose 11.40 dollars to 1,132.10 dollars an ounce.
