Rare earth elements (REEs) are known for their specialized optical and electronic properties that have led to their use in a wide range of applications, such as luminescent fibers employed in security papers (e.g., bank notes). Most of the security documents are disposed at the end of ...
E. et al. Recycling rates of metals — a status report, a report of the working group on the global metal flows to the international resource panel (UNEP, 2011). Balomenos, P. et al. The EURARE project: development of a sustainable exploitation scheme for Europe’s rare earth ore ...
Here are electronics parts from old computers. Recycling the rare-earth metals in these parts might help meet demand for these highly valued materials. ADAM SMIGIELSKI/ISTOCK/GETTY IMAGES PLUS Our modern lives depend on metals kno...
Rare Earth Metals Recycling Market The global rare earth metals recycling market size was valued at USD 248 million in 2021 and is projected to reach USD 422 million by 2026, growing at a cagr 11.2% from 2021 to 2026. The demand for these elements is likely to rise over the forecast peri...
This leads to an oxidation of the iron and thereby of a destruction of the matrix where upon other metals could go in solution. Bioleaching is used industrially mainly for the extraction of Cu, Ur or Au out of low-grade ores. About 10–20% of the worldwide copper production is recovered...
What are rare earth metals? “Rare earths” is the name given to a group of 17 metals in the periodic table of elements. The name is slightly misleading because they are not actually rareper se; in fact, they are relatively abundant. Their rarity lies in the fact that they are ...
metals. Additionally, rare-earth metals are important alloying addition to steels. The commitment to clean energy technologies by governments and the projected growth in power and transportation sectors across the globe ensure that the demand for ...
Rare earth metals, commonly used in the production of high-tech goods, are desperately needed for the European economy. China has a monopoly on the supply of these metals, producing up to 97% of the world's supply. In July, China placed export restrictions on gallium and germanium metals,...
Hitachi was selected by Japan's Ministry of Economy, Trade and Industry to participate in its project to promote recycling of resources, launched in fiscal 2009. The project's goal is to find technology for recycling rare earth metals from "urban mines," such as high-performance magnets from ...
Salmon semen has the benefit of being both cheap and green. Even better, experts say the discovery could be applied to recycling rare earth metals used in smart phones, computers and electronic circuits—metals that otherwise would end up in a landfill. ...
