BHP’s treatment, refining costs with large Chinese smelters rise 25%

Large copper smelters in China settled term treatment and refining charges with global miner BHP Billiton Ltd at $90 per tonne and 9 cents per pound respectively for delivery in the second half of this year, a smelter source said on Friday.

The second-half treatment and refining charges, or TC/RC, will nearly double from the same period of 2010 and represent a rise of 25 percent from about $72 for the first half of 2011. The term TC/RC for the full year 2010 was $46.5 and 4.65 cents.
