  • Additional Positive Metallurgical Test Results Improved

    Recrushing of the intermediate grade gravity middlings fractions has been shown on a number of projects to liberate more spodumene and result in increased recoveries The middlings fractions from this test were recrushed at 335mm and put through the DMS again and the combined result showed ecovery of 75% a r recovery at a grade of 588%The results show that at a top size (p80) of 1 mm, >70% Sn recoveries are achieved for enhanced gravity concentration, >85 % Sn reports to middlings and concentrate during spiralling, and shaking tables achieve at least 85% recovery, giving >50% cumulative recoveries and a final concentrate grade of 7459% SnO2 (5875% Sn)Investegate |Bushveld Minerals Ld Announcements |Concentrate Middlings Tails (%) SKGPM1 Gravity Separation XRD Chlorite Quartz Amhibole Plagioclase Calcite Dolomite Magnesite Magnetite Talc Pyrrhotite Pyrite Chalcopyrite Ilmenite Pentlandite Gravity data –TZ1 Co conc relative to starting material Gravity data –TZ1 Co & U removedKonttijärvi Battery Mineral geometallurgical case study
