Outstanding results from initial HLS testwork support project's commercial potential
Seymour Lake: Preliminary Testwork Shows Potential to Produce High-Grade Lithium Concentrate Grading Up To 7.73% Li2o
Perth, Feb 9, 2017 AEST (ABN Newswire) - Lithium and graphite explorer Ardiden Limited (
ASX:ADV) is pleased to advise that it has received highly encouraging preliminary testwork results from Independent Metallurgical Operations (IMO), based in Perth, Western Australia for ore samples from its the majority-owned Seymour Lake Lithium Project in Ontario.
HIGHLIGHTS:
- Initial Heavy Liquid Separation (HLS) testwork on Seymour Lake spodumene returns excellent results, produced high grade lithium concentrate up to 7.73% Li2O.
- The preliminary tests show spodumene particles are well liberated at relatively course size.
- Testwork is ongoing to develop a suitable processing flowsheet.
The HLS testwork results from the spodumene samples provided to IMO indicate that the spodumene particles are well liberated at relatively course size. Lab HLS tests produced 7.73% Li2O concentrate. Empirically, pure spodumene is considered to be 8.03% Li2O, indicating Ardiden's lithium concentrate is very close to the pure form.
The production of the lithium concentrate at such a high grade is well over the industry standard of 6% Li2O, as required by most lithium end-users.
These preliminary testwork results are very encouraging and once again confirm the high quality of the Seymour Lake spodumene. So far, the results indicate that there appears to be minimal gangue minerals in the concentrate, with Fe2O3 and TiO2 of 1.03% and 0.03% respectively.
Ardiden confirms that as these are only the preliminary tests and further work is required to define the process flowsheet to produce the final lithium concentrate.
Ardiden are now are investigating various extraction process options including gravity, flotation and magnetic separation processes to develop optimum process flowsheet for the project.
