BEIJING, Aug 5 (Reuters) - Copper and most other base metals found support from a weaker U.S. dollar amid expectations of slower U.S. job growth in July ahead of an employment report due later on Friday.
Three-month copper on the London Metal Exchange rose 1.2% to $7,821.50 a tonne as of 0746 GMT.
Copper prices recorded a three-day loss earlier this week on weak global factory data and flaring U.S.-China tensions following U.S. House of Representatives Speaker Nancy Pelosi's visit to Taiwan.
The recent rebound was primarily attributed to technical buying and a weaker dollar on signs of a softening labour market.
A weaker dollar translates to cheaper costs for commodity buyers using other currencies.
However, overall sentiment remained bearish with concerns over a prolonged interest rate hike by the U.S. Federal Reserve and near-term demand outlook in China, the world's top metals consumer.
"With the likelihood of Fed raising rate by 50 to 75 basis points hanging on the table, participants are looking to eliminate their risk exposure to current price volatility," He Tianyu, a copper analyst at CRU Group, said.
The most-traded September copper contract on the Shanghai Futures Exchange advanced 1.5% to 60,310 yuan($8,938.66) a tonne.
LME tin gained 0.6% to $24,700 a tonne, zinc rose 0.9% to $3,480.50 a tonne, aluminium increased 1% to $2,427 a tonne, while lead nudged up 0.2% at $2,048.50 a tonne.
ShFE zinc jumped 4% to 24,600 yuan a tonne, nickel climbed 2.5% to 177,260 yuan, tin rose 2.2% to 197,500 yuan a tonne, and aluminium was up 1.8% to 18,515 yuan a tonne.
