Australian mining company Lynas Corp is building a plant in Malaysia to process rare earth oxide (REO) from its Mount Weld mine in Western Australia.
REOs were mined from the Mount Weld site and operations completed in 2008. More than 773,300 tonnes of ore, with an average grade of 15.4% Rare Earths Oxide, were extracted.
Despite the name, REOs are fairly common. They get their named from the fact that they are quite often well dispersed and not economically viable to exploit. REOs from Mount Weld can be typically used to produce superalloys for jet engine components, gas turbines, rocket subassemblies, and heat resisting and combustion equipment.
Mount Weld is located 35 kilometres south of Laverton, Western Australia. It is the richest known deposit of Rare Earths in the world. The initial mining campaign was successfully completed in June 2008 and was accomplished lost-time-injury free, on budget and ahead of schedule.
