Shanghai Futures Exchange copper pulled back from early gains on Tuesday to finish up 1 percent at 48,920 yuan ($7,108) a tonne on Monday as the dollar pushed ahead, but ongoing supply concerns from industrial action in Chile and an Indonesian export permit dispute underpinned prices.
Other metals were also buoyed by supply concerns, with Shanghai zinc leading sister metal lead up around 2 percent, following gains in London overnight after a steep fall in available zinc inventory on the LME and concerns over mine supply.
