[{"type":"text","content":"Highlights Heavy Liquid Separation (“HLS”) tests on a 2 ton bulk samples taken from the K-dump produced a 6+% LiO spodumene concentrate at four different size classifications. HLS tests produced a 6.5% Li2O spodumene concentrate at overall lithium recoveries exceeding 60%. Fe content of +- 1.3% in final spodumene concentrate to be reduced further with magnetic separation in Phase 2 testworks. HLS testing is the industry standard lab bench scale testing to establish if physical metallurgy will be sufficient to beneficiate mineral deposits into sellable concentrates. In the K- dump, LiO, Sn and Ta are evenly distributed across the different size fraction from -5mm to +45 µm. Lithium recoveries increased with size fraction while tin and tantalum had improved recoveries in the finer fractions which indicated that the tin and tantalum required further liberation to improve recoveries. Upstream classification, Dense Media Separation (“DMS”) and gravity concentration technologies will be evaluated during the Phase 2 testwork program to design the optimal plant for lithium, tin, and tantalum extraction. Toronto, Ontario – TheNewswire - September 13, 2022 – Tantalex Lithium Resources Corp. (CSE:TTX) – (FSE:DW8) – (OTC:TTLXF) (“Tantalex” or the “Corporation”), is pleased to announce the results of the metallurgical testwork on a 331 kg composite bulk sample (sub sample of the approx. 2 tonne sample taken from drillholes locations MDC047, MDC056 and MDC 064 ) collected from the K-dump at the Manono Reclamation Project located in the Tanganyika province of the Democratic Republic of the Congo (“DRC”). Mineralogical analysis indicated that nearly all the lithium is contained in Spodumene. It was further determined that Cassiterite is the only tin bearing mineral and in the case of tantalum the overwhelming majority occurs as Tantalite with low concentrations of Tapiolite. The HLS tests have resulted in 6+% Li2O spodumene concentrates at high lithium recoveries exceeding 60% and an iron content of approximately 1.3% Fe2O3 without conducting any magnetic separation on the concentrate produced. Although HLS results are only an indication of a DMS circuit’s performance in operation, the results indicate that DMS will be applicable to the Project’s flowsheet as a primary driver for lithium recovery in the coars...
