Refractory gold ores present significant challenges to conventional extraction methods. In these ores, gold is tightly encapsulated within sulphide minerals or locked by carbonaceous matter ...

Freegold Ventures (TSX: FVL; OTCQX: FGOVF) shared results from its ongoing metallurgical test work. Studies demonstrated that all three methods tested—BIOX, POX, […] ...

Gold recovery from carbonaceous ores represents a significant challenge in mineral processing due to the inherent presence ... Ore characterised by high levels of both sulfide and carbonaceous ...

All three methods tested: BIOX®, POX, and the Albion Process™ yield over 90% gold recovery; Further work to enhance sulphide recoveries through oxidation, as well as gravity, flotation and CIL ...

Cyanidation of sulfide concentrate re-ground to P 80 at 29 µm and 16 µm returned gold recoveries of 62.0% and 82.9% respectively. Overall, an average gold recovery of 84.8% was achieved after a 48 ...

The corresponding cleaner tail was another 7.4% of the feed weight, assayed 40.6 g/t Au, 898 g/t Ag and 16.04% sulphide sulphur and represented additional recoveries of 46.5% gold, 31.5% silver ...

Flotation testing conducted on material with a P 80 grind size of 83 μm achieved a gold recovery of 89.5%. Cyanidation (‘CN’) testing done on flotation tailings material yielded a maximum gold ...

Overall, an average gold recovery of 84.8% was achieved after a 48 hour processing cycle involving a combination of gravity recovery, sulfide flotation, regrind of sulfide concentrate to P 80 at ...
