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 ...

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 ...

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 ...

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 ...
