  Enhanced flotation of refractory gold ore by using sulfur-oil ...

  201671 · Abstract In this study, a new approach “sulfur-oil agglomeration” for gold flotation was put forward to recover gold particles in laboratory and industrial scale experiments. The optimum recovery of gold was obtained by adding (NH 4) 2 S 2 O 3, oil emulsions and sulfur into the mill, together with butyl xanthate as the collector in weak …

  Post-regrind selective depression of pyrite in pyritic copper–gold ...

  201531 · The present study investigates the effect of aeration and diethylenetriamine (DETA) on the selective depression of pyrite in a porphyry copper–gold ore, after regrinding (at grind sizes, d80 = 38 and 8 μm) with respect to Au recovery and grade using oxygen demand tests, flotation, QEMSCAN, X-ray spectroscopy (XPS) and EDTA extraction …

  Combined Column and Mechanical Flotation Cell Process for …

  2021123 · A concentrate with an average grade of 30.0 g/t gold was obtained using the mechanical flotation cell process, while the total recovery was between 90 and 95%. For the purposes of increasing the production of gold, shortening the process and increasing production efficiency.

  Flotation of gold and gold-bearing ores - ScienceDirect

  200511 · Aerofloat 6697 provided the best gold concentrate grade at pH values less than 11.5 while Aerofloat 7249 and Aerofloat 208 were better at pH values above 11.5 and gold grades in excess of 250 g/t were generated.

  Improving Extraction Efficiency from Witwatersrand Gold …

  2024613 · The sulfides are separated by means of a flotation circuit and that resulting concentrate is subjected to a regrind of below 20 μm to enable a greater liberation of the gold. The ultra-fine material is then subjected to a dedicated leach circuit to recover the now exposed gold particles.

  Beneficiation of the gold bearing ore by gravity …

  2017828 · The flotation results showed that the enrichment ratio of gold was relevant to that of carbon, indicating that gold occurred in close association with carbon. A concentrate containing gold 7.26 g/t and carbon 12.37 % was obtained, with gold recovery 83.10 % and carbon recovery 90.24 %.
