Hace 4 días · Guangjun Mei. Abstract. Most rare-earth metals and alloys in the world are produced through molten salt electrolysis, resulting in the creation of a substantial amount of rare-earth melt electrolysis slag (RMES) that contains high levels of rare-earth elements (REEs) and holds significant recycling value.

Hace 1 día · Aluminum is produced from its primary bauxite ore through the Bayer process. Although Al is important nowadays in the development of humanity, its production leads to the generation of a huge amount of waste, called red mud. Globally, the estimation of the stock of red mud is about 4 billion tons, with about 10 million tons located in Turkey. The presence of rare-earth elements (REEs) in ...
Hace 2 días · Carl Spandler, a professor of Earth Sciences at the University of Adelaide, says Australia’s potential in the rare earths sector is “enormous”. “Australia is one of the few countries outside of China with an active REE mining sector,” he adds. “The Mount Weld deposit alone accounts for approximately 5% of the world supply of REEs.
Hace 3 días · The Diamond Creek prospect area sits eight miles northwest of Salmon, Idaho, and is estimated to hold about 75,500 tons of total rare earth oxides (TREO). The latest exploration results in Lemhi ...
Hace 5 días · She said: “These findings challenge the models previously applied to rare earth mineral formation. Our research highlights the dependence of crystallisation pathways, mineral formation kinetics, and chemical texture on a myriad of factors, including rare earth concentrations, ionic radii, temperature, time, and host grain solubility.”
Hace 4 días · Rare earth elements (REE) include 17 metallic elements in the middle of the periodic table collectively known as Lanthanides. All have unusual fluorescent, conductive, and magnetic properties and are often used as alloys in chemical catalysts (e.g., air pollution control), defense products, components of electric car batteries, and consumer electronics (e.g., cell phones).
