Copper market’s biggest whale fuels speculation of a major shift
The world’s single biggest buyer of copper, State Grid Corp. of China, has slowed its purchases of copper wire this year.
Grupo Mexico and miners at its U.S. copper mining unit Asarco agreed to extend their existing contract for two more years, the Mexican company said in a statement on Tuesday.
The contract covers 2,100 workers at Asarco’s operations in Arizona and Texas and will now be valid until 2013.
