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 ...

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 ...

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 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 one-step, water- acid- and alkali-free method for extracting high-purity lithium from spodumene ore has the potential to transform critical metal processing and enhance renewable energy supply ...

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

Mt Monger Resources Ltd. (AU:MTM) has released an update. MTM Critical Metals Limited has secured exclusive global rights to Flash Joule Heating technology from Rice University, promising to ...

Therefore, employing a metal recovery process based on industrial wastes can mitigate the environmental impact associated with metal production. Additionally, metal recovery generally requires less ...

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 ...

Copper smelting - a critical process in metal production - often generates slag, which contains valuable metals. This slag has historically been thrown away, causing harm to the environment and ...
