Electroplating sludge (ES), a hazardous waste rich in toxic heavy metals, is produced through CaO/Ca(OH) 2 precipitation. Despite its hazardous nature, the sludge is also a valuable secondary source ...

Extraterrestrial mining and metal processing are key strategies for space exploration. In a new study in Scientific Reports, Rodolfo Marin Rivera, and a team of scientists in materials science, ...

A new study led by researchers in Canada introduces a novel process for the extraction and separation of metals from spent alkaline batteries, offering a promising solution for efficient recycling of ...

Modern technology relies on an undisrupted supply of metals, yet many metals have limited geological deposits. Recovering metals from wastewater and brine could augment metal stocks, but there is ...

A new study from the University of Illinois Urbana-Champaign shows how electrochemistry can be used to extract precious metals from discarded electronics in an efficient and environmentally friendly ...

Lithium is essential to the modern world, but its extraction has always carried a ...

The heaviest known elements are the so-called "superheavy" elements, those with atomic numbers greater than 103. These elements are found only in laboratories, where they are made by fusing together ...

Amid rising demand, miners are turning to biotech firms to help them squeeze more metal out of aging mines. In a pine forest on Michigan’s Upper Peninsula, the only active nickel mine in the US is ...

Canadian company Volt Lithium has developed and pilot-tested a new low-cost lithium extraction method to pull this critical battery metal out of low-concentration brines. Now it plans to turn old oil ...

Scientists have unlocked a groundbreaking method for mining metal-rich asteroids using a deep eutectic solvent (DES). In their study, recently published in Scientific Reports, study lead Rodolfo ...
