Kodal Minerals has announced that metallurgical testwork has confirmed high-grade spodumene concentrate at the Bougouni lithium project in Mali.
Highlights: - Metallurgical recoveries range from 80% to 87% for initial flotation testwork
- Spodumene concentrate grades ranging between 5.5% and 6.7% Li2O achieved from multiple batch testing - chemical grade spodumene concentrate (typically containing 6% Li2O) is sold for use in battery manufacturing and other industrial applications
- Mineralisation is recognised as high-grade and of suitable quality for producing lithium carbonate, with low level potassium and sodium content and with moderate iron content
- Initial testwork used flotation tests only, as samples comprised reverse circulation drill chips which contain a significant portion of very fine material not suitable for other techniques
- Further metallurgical test work is planned utilising diamond drill core to seek to further enhance overall recoveries through a comprehensive process utilising gravity separation as well as flotation
- Metallurgical testing completed at the Shandong Ruifu Lithium Co Ltd which operates a lithium carbonate and lithium hydroxide production plant in China Kodal Minerals chief executive Bernard Aylward said: "After a series of extremely encouraging drill results from our Ngoualana prospect and surrounding target areas, this initial metallurgical testwork reinforces our confidence that the Bougouni project has the potential to become a high quality spodumene producer worthy of significant commercial interest.
"These results confirm the ability of the pegmatite hosted mineralisation at Bougouni to generate a high-grade spodumene concentrate with low impurities that is a quality product for future lithium carbonate production.
"This is an important criterion for us to demonstrate, particularly in light of recent increases in the price received for this quality of high-grade spodumene concentrate.
"The initial testwork was completed on RC drill chips collected from the first phase of drilling at the Ngoualana prospect.
"Whilst further test work will be needed using diamond drill core in order to determine the optimal processing route, this initial work has demonstrated the ability to have recoveries in excess of 80% from flotation work to produce commercial grade spodumene concentrate.
"With this in mind I look forward to providing further updates on the metallurgical programme in due course."
