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.
The largest union at Chile’s Escondida copper mine has voted to “indefinitely” extend a strike at the mine, which is controlled by BHP Billiton.
Members of the 2350-strong Escondida Mine Workers Union No 1 “unanimously voted” to extend the work stoppage, which began on Thursday night and was initially planned to end 24 hours later at 8pm on Friday, union leader Jose Vidal said.
