In recent two decades, ultrasound has been broadly applied to the hydrometallurgical
leaching process to recover valuable metals within raw materials, aiming to solve the …

Electronic waste (e-waste) recycling is becoming a global concern owing to its immense
quantity, hazardous character and the potential loss of valuable metals. The many …

In the context of the circular economy, there is a need for advanced methods to recover
metals from industrial waste, yet classical hydrometallurgical techniques are limited. Here …

Lithium-ion batteries (LiBs) have been consumed exponentially due to the rapid growth of
electric vehicles and electronics. Efficient recycling of spent LiBs is crucial for sustainability; …

The recycling of spent lithium-ion batteries can not only reduce the potential harm caused by
solid waste piles to the local environment but also provide raw materials for manufacturing …

Cavitation is one of the major effects of UAL, associated with a variety of phenomena and
physical aspects such as chemical, mechanical, and thermal. Cavitation, categorized as an …

As the world dabbles with increasing quantities of spent lithium-ion batteries (LIBs) and the
need to recover valuable metals therein, sustainable approaches to achieving this need …

In this paper, mechanical stirring and ultrasonic treatment are used to separate graphite
electrode materials from copper foils in recycling spent lithium-ion batteries (LIBs). Firstly …

6 Million metric tons of spent carbon electrodes modify carbon-rich solid wastes from
aluminum electrolysis are produced annually, threatening ecosystems by cyanide and …
