BEIJING, March 30 (Reuters) - China's top copper smelters agreed on a guide price for treatment and refining charges (TC/RCs) for copper concentrate processing in the second quarter of 2023 at $90 per tonne and 9.0 cents per pound, two sources with knowledge of the matter said on Thursday. The rates were decided at a meeting of the China Smelters Purchase Team (CSPT) held on Thursday, the sources said. The new prices are lower than the guidance for the charges set at $93 per tonne and 9.3 cents per pound for the first quarter this year.
