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 ...

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 ...

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 ...

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 ...

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 ...

A team at Rice University has unveiled a fast and cleaner method to extract aluminum and strip toxic metals from bauxite residue, also called red mud. The hazardous by-product of aluminum production ...

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 ...

A plan may finally be in the works to cap an alumina plant's piles of toxic and slightly radioactive "red mud" that have littered neighborhoods with dust for years along the Mississippi River south of ...

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 ...
