Most people are familiar with rechargeable batteries, hybrid vehicles, renewable energy (such as wind turbines), mobile phones, flat screen display panels, laptop computers, compact fluorescent light bulbs, disk drives & catalytic converters, but it is not widely known that these products, amongst many others, are dependent on the unique properties of Rare Earth Elements.
The use of rare earth in magnets, rechargeable batteries and catalysts accounts for more than 60% of REE consumption with demand expected to increase significantly in all these areas.
