Jan 10 (Reuters) - Prices of most base metals fell on Tuesday as traders gauged the risks of a global economic downtrend and weak consumption, shedding gains logged in the previous session after top consumer China reopened its borders.

Three-month copper on the London Metal Exchange was down 0.9% at $8,785 a tonne, as of 0741 GMT, while the most-traded March copper contract on the Shanghai Futures Exchange closed up 1.5% at 66,590 yuan ($9,813.57) a tonne, tracking overnight gains in London.

LME aluminium dipped 0.7% to $2,421 a tonne, zinc declined 1.4% to $3,161.50 a tonne, lead fell 1% to $2,228.50 a tonne and tin shed 1% to $25,600 a tonne.

SHFE lead declined 0.2% to 15,530 yuan a tonne, tin was down 1% at 203,480 yuan a tonne, while aluminium rose 1.4% to $18,160 a tonne and zinc climbed 1.8% to 23,735 yuan a tonne.

Base metals prices rose strongly on Monday, driven higher by an improving demand outlook after top consumer China reopened its border after years of restrictions due to the COVID-19 pandemic, boosting LME copper to its highest in more than six months.

But fundamentally, the global economy is still at risk of a recession and the U.S. dollar could still firm up even more amid prospects of further interest rate hikes, making greenback-priced metals more expensive to holders of other currencies.

"(Prices) went too high last night. I am neutral to bearish short term. I don't see strong prices till at least Q3," said a broker.

Physical demand of metals is also expected to slow as China is about to enter its week-long holiday break to celebrate the Lunar New Year during Jan. 23-27.

Yangshan copper premium , which indicates demand for imported copper into China, fell to $37.50 a tonne on Monday, from $152.50 a tonne seen less than three months earlier.

SHFE nickel hit a one-month low of 204,180 yuan a tonne on rising supply worries after Bloomberg reported that nickel producer Tsingshan is looking to boost refined nickel output in China from intermediate forms like ferronickel.
