With the surging demand for AI and electronic devices, indium resources are becoming increasingly scarce. Recycling indium from discarded electronics, photovoltaic (PV) panels, and industrial waste has emerged as a crucial solution—not only reducing mining costs but also advancing the future of green technology.…
“Black, unrefined selenium is now skyrocketing in value—transforming from industrial waste into a ‘new goldmine’! Breakthroughs in purification technology have slashed costs while boosting purity, and booming demand from photovoltaics, semiconductors, and other industries means recycling crude selenium can net…
Abstract Ruthenium (Ru), a critical member of the platinum group metals (PGMs), exhibits unique advantages in catalysis, electronics, and high-temperature materials, including: However, its limitations include: Future demand will be driven by Ru’s potential in hydrogen energy catalysts (e.g., HER) and ultra-high-density storage media. 1. Comparative…
Abstract Rhodium (Rh), a critical member of the platinum group metals (PGMs), is an ideal material for extreme environments due to its high melting point (1964°C) and density (12.41 g/cm³). These properties stem from its face-centered cubic (FCC) crystal structure and strong metallic bonding derived…
Abstract Rhenium (Re), a high-melting-point rare metal, is primarily recovered from byproducts of copper-molybdenum smelting, flue dust, and spent catalysts. Industrial production relies on hydrometallurgical processes, including: Additional pyrometallurgical roasting activation is often employed for pre-treatment. High-purity rhenium (≥99.99%) is obtained via hydrogen reduction or…
