Australian researchers at CSIRO and Swinburne University have developed a method to extract iron from Martian soil using high-temperature pyrolysis, potentially enabling on-site resource utilization for future Mars missions and colonization.
A potentially sustainable process has been developed to treat the hazardous waste of aluminium production, known as 'red mud', and extract iron from it for making steel. This process not only addresses the environmental issues associated with aluminium production waste but also has the potential to contribute to carbon-neutral steel production, thereby increasing the sustainability of both major metal industries.
Red mud, a by-product of aluminium production, is a major environmental issue due to its accumulation and disposal. A new study proposes using hydrogen plasma to directly extract iron from red mud, offering a sustainable and carbon-neutral method for steel production. The process involves exposing red mud to a lean hydrogen thermal plasma, resulting in the production of liquid iron without the need for prior treatment. This innovative approach not only extracts valuable iron but also renders the residual material into a neutral product suitable for other industries, addressing both the issue of red mud waste and the production of iron without direct CO2 emissions.
