Laboratory demonstration tests were run with coarsely ground of FI ore samples. A 36% copper concentrate with 7.2 ppm (0.27 oz/t) gold was produced for a 34% copper recovery and 13% gold recovery. Other tests had gold recovery as high as 45%. Concern 1 (metallurgy) was alleviated.
Flotation of Gold and Gold-Bearing Ores
Gold particles in an ore deposit will vary in size from large nuggets to particles locked in the crystal lattice of sulfide minerals. These sulfide minerals are referred to as gold carrier minerals and contain trace to minor amounts of gold (Taggart, 1927, Chryssoulis and Cabri, 1990).Often it is found that gold ores are refractory due to the small size of the gold …

Coarse particle flotation: A review
Miller et al. (2016) performed a comparative study using gold bearing sulphide ore against a lab-scale mechanical flotation cell. The result shows that a laboratory-scale HydroFloat™ can float 500–800 µm particles with just 1 % surface liberation, and zero particles were reported in the tailings stream with a liberation percentage of more ...
Gold Ore Flotation Considerations and Influencing Factors
Gold ore flotation extracts gold particles from ore by utilizing gold's hydrophobicity and gangue minerals' hydrophilicity. While the process can effectively recover gold, several precautions should be taken to ensure its success and safety. Here are some precautions for gold ore flotation. Proper lab testing
