Research also highlighted hydrometallurgical schemes for pure copper extraction from waste materials. Strategic & Sustainable Importance
The symposium covered a wide range of elements that are crucial but produced in low tonnages compared to major metals like iron or copper. Rare Metal Technology 2019
Rare metals are indispensable across various sectors due to their unique magnetic and luminescent properties. Rare Metal Technology 2019 | Springer Nature Link Rare Metal Technology 2019 | Springer Nature Link
Methods discussed included supercritical fluid extraction and biosorption of precious metals. Recovering metals from secondary sources like e-waste and
As the industrial demand for REEs grows, especially for carbon-neutral technologies, the focus has shifted toward finding alternative and sustainable sources.
Rare earth metals (e.g., yttrium, scandium), platinum group metals, gold, vanadium, cesium, and tungsten.
Recovering metals from secondary sources like e-waste and waste printed circuit boards is becoming a necessity to meet future requirements.
