    2013-8-9 · The total gold recovery varies between 73% and 75%, which is far lower than gold recovery in the baseline flotation studies (copper plus pyrite flotation). This is due to depression of pyrite which has been identified from the mineralogical characterisation as the major gold host mineral in the ore.

  • A review of the flotation of native gold and electrum ...

    Abstract Native gold and electrum are naturally-occurring alloys containing gold and silver and a little copper. They are the most common and important forms of gold in ores. Their recovery by gravity concentration, cyanidation, or flotation from ores, typically containing 0.1–20 g/t Au is of great commercial importance. This paper reviews the literature on their recovery by flotation.

When the feed rate varied between 0.42 and 0.58 t/h, the recovery of gold was essentially flat (approximately 94.5%). However, the concentrate gold grade at a feed rate of 0.58 t/h was much higher than that at 0.42 t/h.
