A step toward cleaner iron extraction using electricity
- Advertisement -
Iron and its alloys, such as steel and cast iron, dominate the modern world, and there’s growing demand for iron-derived products. Traditionally, blast furnaces transform iron ore into purified elemental metal, but the process requires a lot of energy and emits air pollution. Now, researchers report that they’ve developed a cleaner method to extract iron from a synthetic iron ore using electrochemistry, which they say could become cost-competitive with blast furnaces.
