Lynas Nears Production at Malaysian RE Plant

Lynas Corp. reported in early January that it had successfully commissioned the cracking and leaching units at its Lynas Advanced Materials Plant (LAMP) in Malaysia. The process was achieving recov-ery rates of more than 90% of contained rare earth oxides through the cracking units. The mixed rare earths sulphate pro-duced was being fed to the plant’s solvent extraction units for ultimate production of individual rare earth products.

Lynas anticipated that commercial rare earth products would be available within a few weeks, with ramp up to design produc-tion to take place over the next three months.

As a consequence of commissioning of the cracking and leaching process, the Lynas plant was also producing sufficient quanti-ties of solids residues to start production of synthetic gypsum and aggregate co-prod-ucts. These products are being subjected to testing and market trials. The plant process-es rare earths oxides concentrate produced at Lynas’s Mount Weld mine and concentra-tor 35 km south of Laverton, Western Australia. Initial production capacity is 11,000 mt/y of separated rare earths oxides, with provision for expansion to 22,000 mt/y.

The LAMP was essentially completed during the first half of 2012, but commis-sioning was delayed by a series of court actions by individuals living near the plant, who had concerns about the potential impact of the plant on the environment.
