Rio Tinto Alcan testing technology at Alma

摘要

Rio Tinto Alcan Inc. has launched a research and development project to test the use of high amperage in electrolysis at its Alma aluminum smelter in Saguenay, Quebec, which could increase production capacity without an investment in new equipment. The AP44 smelting technology will be an upgrade from the AP30 technology at the smelter, effectively allowing cells to operate at 440,000 amperes instead of 300,000 amperes, the company said.
