Global Advanced Metals, formerly known as Talison, has reopened its Wodinga and Greenbushes operations.
Originally placed into maintenance during the global financial crisis in 2008, these sites are the world’s largest producers of tantalum and lithium.
It produces approximately 1.4 million pounds of tantalum peroxide annually, around a third of total global supply.
Currently, crushing facilities at the site are in use by Atlas Iron.
An agreement between Atlas and Global will see the miner recommence using its infrastructure in a sharing capacity.
Global chief executive Bryan Ellis said that market conditions and the supply chain had altered significantly during 2010 and that it had secured contracts enabling it to restart mining and processing.
“There has been strong growth in all sectors of tantalum demand and stockpiles are rapidly diminishing, with Global Advanced Metals the only producer able to fill the supply chain quickly,” Ellis said.
