Sept 25 (Reuters) - Copper prices on Friday rebounded from a one-month low hit in the previous session, as a weaker U.S. dollar boosted the appeal for greenback-priced metals, while hopes of more stimulus in the United States also aided the sentiment.

The dollar dipped from a two-month peak, but was on track for its biggest weekly gains in near six months as doubts persisted on whether Washington can overcome divisions to agree on a stimulus package.

Three-month copper on the London Metal Exchange rose 0.8% to $6,578.50 a tonne by 0432 GMT. However, it was on track for its first weekly loss since early August.

The most-traded November copper contract on the Shanghai Futures Exchange ended the morning session up 0.1% at 50,900 yuan ($7,466.63) a tonne.

Democrats in the U.S. House of Representatives are working on a $2.2 trillion coronavirus stimulus package that could be voted on next week, a key lawmaker said on Thursday.

"The constant calls from Fed officials to provide additional fiscal support to the economy seemed to (have) jolted lawmakers into action," ANZ analysts said in a note.

"But it is difficult to see a material package being agreed given election-related tensions in Washington," said James Knightley, chief international economist at ING.
