source:SMALL CAPSAssays from rock chip sampling at Reach Resources’ (ASX: RR1) Wabli Creek project in Western Australia have identified a primary source of high-grade niobium / rare earth element-enriched pegmatites, previously only found in surface eluvial samples on site.The granitic pegmatites have been confirmed as a primary source of mineralisation with the best assays of 17.65% niobium oxide, 0.15% yttrium oxide, 10.81% tantalum oxide, 31.39% titanium oxide and 0.37% TREO (total rare earth oxides).The results, chipped straight off the bedrock, hold similar concentrations to previously-re...

source:IMC University of Applied Sciences KremsA research collaboration between BOKU Tulln and IMC University of Applied Sciences Krems is using the further development of bioleaching and bioaccumulation to develop a two-stage, environmentally friendly and sustainable process for recovering rare earth elements (rare earths).In the bioaccumulation step, metal recovery rates of up to 85% were achieved from electronic scrap. The key to success lies in the combination of biotechnological processes. The promising foundations for these methods, which are currently under development, were recently pu...

source: Oak Ridge National LaboratoryWhen element 61, also known as promethium, was first isolated by scientists at the Department of Energy's Oak Ridge National Laboratory in 1945, it completed the series of chemical elements known as lanthanides. However, aspects of the element's exact chemical nature have remained a mystery until last year, when a team of scientists from ORNL and the National Institute of Standards and Technology used a combination of experimentation and computer simulation to purify the promethium radionuclide and synthesize a coordination complex that was characte...

source:phys.orgA team of material scientists led by Jiang Li from Shanghai Institute of Ceramics, Chinese Academy of Sciences, in Shanghai, China recently reported (Tb1-xYx)3Al5O12 magneto-optical ceramics with high optical quality. The optical transmittance, microstructure, Verdet constant, and thermal conductivity of (Tb1-xYx)3Al5O12 with different Y content were investigated in detail.It was found that Y2O3 can suppress the secondary phase and improve the optical quality of TAG ceramics. As optical quality occupies one of the most important parts of the practical performance of magneto-opti...
