It is reported that a senior executive of China Minmetals Corporation on Tuesday called for the establishment of a joint organization of Chinese zinc smelters to negotiate with miners on zinc concentrate supply and pricing in the light of the existing joint negotiation group on copper raw materials in China. "We want to build a healthier market," he said. “The aim of this proposal is for Chinese zinc smelters to agree on a TC benchmark price for zinc concentrates in the future. We need more support from smelters now. "
