Global Lithium hits higher recovery at Manna

Global Lithium Resources has welcomed spodumene recovery grades greater than 97 per cent across a range of ore samples at the Manna project in Kalgoorlie, WA.

These results were confirmed by QEMSCAN mineralogical analysis, which also identified high iron rejection at greater than 90 per cent across a range of bulk samples.

Additionally, lithium recovery from ore sorting of low-grade ore increased from 0.56 per cent to 0.90 per cent lithium oxide, which Global Lithium said has the potential to enable lower-grade ores to be economically processed.

Incorporation of ore sorting technology into the overall process flowsheet also increased mill feed grade from 1.0 per cent to 1.2 per cent lithium oxide.

“This final round of trials confirms ore sorting is highly amenable to the Manna lithium deposit,” Global Lithium project director Tony Chamberlain said.

“The technology has demonstrated impressive spodumene recoveries, while rejecting a large percentage of associated waste material.

“Ore sorting will provide greater flexibility to our mining operations and will allow lower cut-off grades to be economically mined and processed at Manna.

“With ore sorting now being incorporated into the main flowsheet, this will enable the project to potentially deliver a higher annual production quantity of spodumene concentrate.”

Chamberlain expects these positive outcomes to be incorporated into the Manna definitive feasibility study, expected later this year.
