Lithium production starts at Bald Hill

Bald Hill DMS plant

Joint venture partners Tawana Resources and Alliance Mineral Assets have launched lithium production at the Bald Hill mine in the Eastern Goldfields of Western Australia.

The spodumene concentrate production has been achieved through a newly-constructed dense media separation (DMS) circuit, which will be ramped up to its full production rate over several months.

Tawana managing director Mark Calderwood said Bald Hill progressed from maiden lithium resource to production in nine months, including only seven months of construction from the ground up.

“The focus now is to achieve steady state production from the stage one DMS circuit and optimise lithium yields,” Calderwood said.

“Concurrently, the JV will work on completion of the stage two lithium fines circuit design and re-commissioning of the tantalum circuits.”

Recent activities completed at Bald Hill have included: water commissioning; practical completion achieved by EPC contractor, Primero Group; ferrosilicon media introduced to the plant and stabilised; crusher commissioned and 20,000 tonnes of crushed ore stockpiled; first ore fed into the processing plant; and first production of spodumene concentrate.

The JV expects to deliver first lithium concentrate from Bald Hill next month.
