LONDON Copper rose on Tuesday, rebounding from a near 2-month low hit in the previous session, supported by a weak dollar and some cautious industrial buying, but concerns about sluggish demand from top consumer China capped further gains.
Three-month copper on the London Metal Exchange (LME) closed at $7,720 a tonne, recovering from a near 2-month low of $7,670 on Monday, when it closed at $7,699.
Trading volumes were low however, as Sandy, one of the biggest storms ever to hit the U.S., forced evacuations and shut down transportation.

A weak dollar makes commodities priced in the U.S. unit cheaper for holders of other currencies.
With prices of most metals near 2-month lows on Monday, some industrial buyers had been tempted, traders and analysts said.
"We are seeing a bit more buying interest from consumers at this sort of price levels but we still see copper physical demand as relatively soft," Standard Chartered analyst Daniel Smith said.
"I don't think demand in China has got any worse, but people are recognizing that growth in quite soft. Realism is starting to sink in."
Prices for the metal rallied nearly 8 percent in September, fuelled by the third round of quantitative easing (QE) by the U.S. Federal Reserve, the promise of bond buying by the European Central Bank (ECB) and stimulus measures in Japan and China.
Copper then weakened in October as expectations that real demand for metals would improve failed to materialize. It is down close to 6 percent in October and is trading up just 1.7 percent in the year to date.
Fundamentals have turned a bit weaker for base metals, as slower economic growth in China weighed on its metals demand, and with metals stocks rising, especially for aluminum and copper,
Benchmark aluminum closed at $1,909, from $1,897 on Monday.
Stocks of aluminum in warehouses monitored by the LME and by the Shanghai Futures Exchange (ShFE) have built up significantly in the last few weeks.
Bonded stocks of aluminum in China have also increased noticeably, a trend which is not likely to reverse anytime soon as new smelters bring additional capacity on stream, analysts added.
"The rise in stocks is due to the pace of growth in local production significantly outstripping the pace of growth in demand," Commerzbank said in a research note.
Hurt by low prices for aluminum and rising costs, China's top aluminum maker Aluminium Corp of China Ltd, Chalco< posted its fourth straight quarterly net loss in the third quarter.
Battery material lead CMPB3 ended at $2,042 a tonne from Monday's close of $2,007.50.
Lead backwardation, or premium of the cash contract against the three-month contract, widened to $4 per tonne from $0.5 on Monday, as battery makers sought scarce supplies of the metal ahead of the peak winter battery replacement season.
Tin ended at $19,800 from $19,555 while zinc ended at $1,855 from $1,825. Stainless steel material nickel closed at $16,050 from $15,950.
