March 10 (Reuters) - Gold prices inched higher on Wednesday, adding to a 2% jump in the previous session after a retreat in U.S. Treasury yields and the dollar lifted the metal's appeal. * The dollar on Tuesday slipped from its 3-1/2-month high as U.S. yields stabilized ahead of key inflation data and Treasury auctions this week. * The U.S. House of Representatives voted on Tuesday to advance President Joe Biden's $1.9 trillion COVID-19 relief bill, clearing the way for the measure to be considered on Wednesday, when it is expected to pass.
