Lynas is an integrated source of rare earths from mine to customer.
Rare earths are essential inputs to high technology, high growth, future-facing industries, especially those involved in energy efficient sectors.
Lynas has a portfolio of aligned assets to explore, develop, mine and process rare earth minerals. These assets are:
Mt Weld – one of the world’s highest grade rare earths mines, located 35km south of Laverton in Western Australia
Mt Weld Concentration Plant – commissioned in 2011 and located 1.5km from the mine site
Lynas Advanced Materials Plant (LAMP) – an integrated manufacturing facility, separating and processing rare earths materials, located in the Gebeng Industrial Estate (GIE) near the Port of Kuantan in Malaysia
The plant at Mt Weld employs a five stage flotation process which is unique to the extraction and concentration of REE and significantly different to the metallurgical process required to extract gold. The Mt Weld product itself is an uncommon mix of metals. Due to the ramp-up process, crushing and flotation is done in batches, with a number of metals being tracked from pit through to concentrate.
The challenge was to implement a cost-effective solution for metal accounting that was scaled appropriately for the Mt Weld operation. The system needed to be uncomplicated, but also able to handle the special requirements of a REE plant. In addition, the Mt Weld operation is certified to ISO 9001 (Quality management systems), so required high standards of data integrity around the tracking of materials through the process plant.
