The test work was completed by German based Dorfner Anzaplan GmbH (\"Dorfner\"), a leading authority in the field of lithium and speciality minerals processing and treatment.\n \nThe Company will continue with additional test work to improve the recoveries of lithium and associated minerals as well as improve the flowsheet design and establishing capital and operating costs for producing lithium from Zulu. \n \n Highlights: \n· The best flotation test work on spodumene pegmatite achieved an overall lithium recovery of 81.8% and a concentrate containing 6.5% Li₂O and 0.09% Fe2O3. This is well within the typical range of spodumene concentrates for glass and ceramics as well as feedstock for conversion to lithium carbonate\n· The best flotation test work on a mixed pegmatite sample achieved a spodumene concentrate containing 5.9% Li₂O being acceptable for spodumene concentrates as feed stock for lithium carbonate production and a commercial grade petalite concentrate containing 3.9% Li2O at exceptionally low Fe2O3 content of <0.01% at an overall recovery in the concentrates of an estimated 70% \n· The tailings of spodumene and petalite flotation process contain very low iron oxide concentrations in the range of 0.01%, offering the potential for producing a high quality, low iron feldspar and quartz as by-products for glass and...
