Rio Tinto is preparing its first shipments of metal from its Kitimat aluminum smelter in British Columbia following an extensive modernization of the facility. The $4.8 billion project will increase production capacity by 48% and result in Kitimat becoming one of the lowest-cost smelters in the world. Rio Tinto is focused on ramping up to an annual production rate of 420,000 metric tons. The modernized smelter is powered exclusively by Rio Tinto’s wholly owned hydropower facility and uses the company’s proprietary AP40 smelting technology, which will effectively cut the smelter’s overall emissions in half.
