Common Applications of Neodymium Magnets
Applications of Neodymium Magnets in the Field of Electrical Engineering More than onethird of the output of the neodymium magnets is used to manufacture various permanent magnet motors The advantages of permanent magnet motors are copper saving, power saving, lightweight, small in size, and high specific power beneficiation methods which may be exploited to recover the REE 2 Material 2and Methods Used 21 coefficient (Material A tailings sample obtained from a South Australian mining operation ∑was used in this investigation ICPMS and QEMSCAN were employed as quantitative tools to characterise the tailings sampleCharacterisation of Mining Tailings for the Beneficiation The largest end uses of REEs are in permanent magnets (neodymiumironboron and samariumcobalt) which find use in wind turbines and electric vehicles, rechargeable batteries (nickelmetal hydride batteries), catalysts (petroleum cracking catalysts, catalytic converters), ceramics, phosphors, metal alloys (Krishnamurthy and Gupta, 2004, Lucas et al, 2014, Xie et al, 2014) and Application of ferrous pyrometallurgy to the hydrogen fluoride (AHF) or fluorine gas, to produce neodymium fluoride from a suitable neodymium substrate is a vital step in the beneficiation of neodymium in an environmentally friendly way Traditional wet methods are known to produce large quantities of waste, formed when aqueous neodymium chloride reacts with hydrofluoric acidFluorination of neodymium carbonate monohydrate with A process is developed for the recovery of neodymium as value added product from magnets of discarded hard disk Under optimized condition, sulfuric acid leaches 98% Nd, 97% Fe, 60% Ni and 75% B Acid leaching was followed by selective precipitation of Nd Recovery of Neodymium as a Value Added product
Comparative Life Cycle Assessment of Neodymium
Neodymium (Nd) is a representative of LREEs In 2018, 170 000 t of rare earth oxide (REO) equivalents were produced worldwide, hereof 120 000 t in China, 20 000 t in Australia, and 15 000 t in the United States 1 The Bayan Obo mine in Inner Mongolia is the largest Chinese REE deposit 2 Regarding the total Chinese REO production, the share of Bayan Obo is approximately 57%Binding increases the solubility of the neodymium over that of the dysprosium, allowing the former to be filtered off Dysprosium is an excellent target for recycling because A Simple Method for the Separation of Dysprosium The reactant used for chemical beneficiation depends on the chemical form of the REM in the mineral ore Thus, REMs contained in bastnäsite are beneficiated by digestion using sulfuric acid, hydrochloric acid and by direct chlorinationMaterial and Energy Requirement for Rare Earth The physical and chemical beneficiation of bestnäsite is different from that of monazite and xenotime, as bestnäsite is a carbonatefluorite mineral while monazite and xenotime are both phosphate minerals The separation of rare earth elements poses many difficulties due to the great similarity of their chemical propertiesGlobal Production Estimation of Rare Earth Elements and Because xenotime carries 847% of heavy REEs (Y, Gd, Dy) in the ore it is more valuable mineral than monazite A beneficiation process was developed which includes grinding, wet low intensity magnetic separation (WLIMS) for removal of magnetite and REEs flotation consisting of one stage of roughing and two stages of cleaningBeneficiation Studies of a Rare Earth Ore from the
