Lighting-like pulses turn toxic red mud into building materials | Researchers have figured out a way to send electric pulses through the mud to purify it and allow it to be reused instead of discarded.
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 allow it to be reused instead of discarded.
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 allow it to be reused instead of discarded. The aluminum-creation process begins with bauxite ore, a raw material that contains desirable aluminum-rich minerals but also a host of impurities including silica and iron and titanium oxides. The mountains and beaches of central Portugal, where he now lives with his wife and two giant poodles, offer the perfect foil for way too much screen time.
