source:MiningThe increasing demand for minerals in clean technologies is meeting concerns over supply gaps. This prompts a re-evaluation of the financial feasibility of recovering minerals left in mine waste that had a low economic value at the time of extraction, writes THERESA SMITH, ESI Africa News Editor.The technological pathways to recover minerals from mine waste depend on the type andcharacteristics of the mine waste and the specific mineral recovered. The mineral extraction process is similar to the original value chain - crushing, milling classification, separation (including flotati...

source:Massachusetts Institute of TechnologyHigh-temperature superconducting magnets made from REBCO, an acronym for rare-earth barium copper oxide, make it possible to create an intense magnetic field that can confine the extremely hot plasma needed for fusion reactions, which combine two hydrogen atoms to form an atom of helium, releasing a neutron in the process.But some early tests suggested that neutron irradiation inside a fusion power plant might instantaneously suppress the superconducting magnets' ability to carry current without resistance (called critical current), potentially c...

source:Helmholtz Association of German Research CentresFlotation is one of the most important processes for separating minerals in the raw materials industry. Achieving the highest possible mineral enrichment requires the appropriate selection and dosage of reagents—a complex, time-consuming and cost-intensive procedure.Researchers at the Helmholtz Institute Freiberg for Resource Technology (HIF), which is part of the Helmholtz-Zentrum Dresden-Rossendorf, have developed a workflow for the economic and ecological optimization and upscaling of flotation reagents. Initial tests on an industrial s...
