Amazon Is Buying America's First New Copper Output In More Than a Decade (wsj.com)
Rio deployed its bioleaching process in the recent restart of a mine east of Tucson and has partnerships to take the technology to several others in the Americas. The idea is to uncork the low-grade ore left behind at old mines and is key to Rio's plans to boost output when new discoveries are harder than ever to bring online and copper demand is surging. [...] "We work at the commodity level to find lower carbon solutions to drive our business growth," said Chris Roe, Amazon's director of worldwide carbon. "That means steel, and that means concrete, and it absolutely means copper with regard to our data centers." Roe said the copper will be routed to companies that produce components for Amazon's data centers. As part of the deal, Amazon is supplying Rio with cloud-computing and data analytics to optimize Nuton's recovery rates and help the miner expand production.
