Copper prices rose on Friday after a three-day slump, supported by a weaker U.S. dollar, but the metal was set for a weekly drop as worries persisted about an economic slowdown in top metals consumer China.

Three-month copper on the London Metal Exchange was up 0.5% at $9,399.50 a tonne, as of 0709 GMT, while the most-traded July copper contract on the Shanghai Futures Exchange ended daytime trade 1% higher at 71,900 yuan ($10,677.64) a tonne.

For the week, copper - which is often used as a gauge of global economic health - was down 0.2%, while other metals also headed for weekly losses.

"Metals marked time with concerns about Chinese demand acting as a weight on sentiment, while the weaker dollar and lift in risk tone acted as support," analysts at Westpac said in a note.

The dollar sank to a one-month low versus major peers on Friday, as traders lowered Federal Reserve rate hike expectations amid signs the U.S. central bank might slow or even pause its tightening cycle in the second half of the year.

A weaker greenback makes metals priced in dollars cheaper for holders of other currencies.

CHINA: Profits at China's industrial firms fell at their fastest pace in two years in April as high raw material prices and supply chain chaos caused by COVID-19 curbs squeezed margins and disrupted factory activity.

ALUMINIUM: Workers at Russian aluminium giant Rusal's Guinea bauxite mine Compagnie des Bauxites de Dian Dian went on strike on Thursday, in a move Rusal said was illegal.

PRICES: LME aluminium rose 0.4% to $2,875.50 a tonne, zinc climbed 0.9% to $3,770, lead added 0.8% to $2,143.50, tin slipped 0.1% to $33,600, and nickel advanced 1.4% to $27,590.

In Shanghai, aluminium rose 1.2%, zinc climbed 1.6%, lead gained 1.1%, while tin fell 0.4%. Low nickel inventory in China lifted the metal by 4.2%.
