source：Bloomberg-In a high-tech twist on hammering pickets into the ground, the U.S. State Department has launched an online tool aimed at staking America’s claim to many of the world’s rare-earth minerals.The U.S. has become increasingly concerned about securing a stable supply of critical minerals used in car batteries, solar panels and wind turbines. Many of those resources are located in emerging markets that may be seen as too risky by American investors looking for “best-in-class” standards.That raises the potential for “two really bad outcomes,” Francis Fannon, the U.S. assistant secret...

source：Daily SciencePermanent magnets are those which retain their magnetic properties even in the absence of an inductive field. Permanent rare earth magnets are the strongest available magnets and are broadly based on two rare earth elements – neodymium and samarium. The rare earth here is a misnomer and these elements are abundantly available in the earth crust. However, due to the difficulty of extraction and high-cost involved in the refining and purification process, these metals are costly. Thus, the application areas for permanent rare earth magnets is limited.The permanent rare earth ...

source：Streetwise ReportsIn a news release, Defense Metals Corp. (DEFN:TSX.V; DFMTF:OTC; 35D:FSEQB) announced that starting in April, it plans to conduct flotation pilot plant processing of the 30-ton bulk sample from its Wicheeda rare earth elements (REEs) property in British Columbia.The company based its decision to proceed with this on the positive results from bench-scale flotation and hydrometallurgical testing, which resulted in development of a flowsheet. It showed that Wicheeda REEs mineralization 'is amenable to relatively simple treatment via well-established flotation and hydro...
