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 ...

New research shows that magnesium and other metals in mine waste can be solubilized and recovered thanks to acid-producing bacteria. Researcher Nathan van Wyk believes that the method has great ...

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 ...

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 ...

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 ...

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

A research team has developed a method to recycle valuable metals from electronic waste more efficiently while significantly reducing the environmental impact typically associated with metal recycling ...

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 ...
