Red mud consists of up to 60% iron oxide. Melting the mud in an electric arc furnace using a plasma containing 10% hydrogen reduces it to liquid iron and liquid oxides, allowing the iron to be easily ...

The production of aluminium generates around 180 million tonnes of toxic red mud every year. Scientists at the Max-Planck-Institut für Eisenforschung, a centre for iron research, have now shown how ...

Red mud, the highly alkaline by‐product of the Bayer process for alumina extraction from bauxite, poses significant environmental and economic challenges due to its vast global accumulation. Current ...

Breakthroughs, discoveries, and DIY tips sent six days a week. Terms of Service and Privacy Policy. Making aluminum is dirty work, and hasn’t improved much since ...

Aluminum is vital for making lightweight cars, beverage cans, and kitchen utensils. But its production creates a by-product called red mud, a caustic slurry containing iron and other metals. The large ...

Aluminum production creates a toxic byproduct known as red mud. In an effort to cut down on this waste, researchers have figured out a way to send electric pulses through the mud to purify it and ...

For years, toxic and slightly radioactive red mud and dust from the waste ponds of a shuttered alumina plant have bothered neighborhoods near Gonzales. But local leaders are working on a solution to ...

An economical process with green hydrogen can be used to extract CO2-free iron from the red mud generated in aluminum production. The production of aluminium generates around 180 million tonnes of ...
