The hydrometallurgical method of copper leaching from scrap electronics is commonly undertaken using pulverized printed circuit boards. Though studies on the use organic acids like citric and oxalic for removal are well documented, those malonic acid rare. Herein, we report investigation efficiencies mixtures hydrogen peroxide unpulverized PCB by Box-Behnken design theoretical determination mos...

The consumption of lithium has increased dramatically in recent years. This can be primarily attributed to its use lithium-ion batteries for the operation hybrid and electric vehicles. Due specific properties, will also continue an indispensable key component rechargeable next decades. An average battery contains 5–7% lithium. These values indicate that used are a high-quality raw material reco...

Granulated blast furnace slag (GGBFS) is a potential resource of rare earth elements (REEs), and due to the complex mineralogy, extraction by conventional hydrometallurgical process makes it an acid-consuming method. Bioleaching thus investigated using chemo-organotrophic bacterium Gluconobacter oxydans (DSMZ 46616) for REE from GGBFS containing 157 ppm Ce, 90 La, 71 Nd 40 Er, hosted in Ca-Al-S...

With the significant rise in application of lithium-ion batteries (LIBs) electromobility, amount spent LIBs is also increasing. LIB recycling technologies which conserve sustainable resources and protect environment need to be developed for achieving a circular economy. Recycling will reduce environmental impact by reducing carbon dioxide emissions terms saving natural raw materials mining. Thi...

Over the past decade, there has been a steady growth in demand for rare metals, with rhenium being one of most highly demanded, but also expensive and difficult to obtain. The high is due its use as key component metallurgical alloys or catalysts used oil refining industry. aggregate facts causes profitability processing rhenium-containing mineral resources, which are copper substandard concent...
