High Gold Recovery Results from Flotation Test Work

2020-7-13  Flotation feed grades were 4.8 g/t and 2.3 g/t gold, respectively. Cleaner concentrate grades ranged from 105 g/t to 637 g/t gold. Flotation gold recoveries ranged from 77% to 80%. Overall recovery (gravity and flotation) for all laboratory tests presented in Table 1 exceeded 90% gold recovery.

Optimisation of gold recovery by selective gold

Gold does float readily, however, and the free gold can be selectively floated away from an ore containing sulphides. This may be an alternative treatment route for gold room applications where fine gold losses can occur when treating gravity concentrates with pyrite and copper sulphides present.

Flotation of Gold and Gold-Bearing Ores - ScienceDirect

2016-1-1  Gold hydrophobicity is enhanced by the addition of flotation collectors, and no flotation plant relies solely on the natural floatability of gold for its recovery. Naturally occurring or free (liberated) gold is optimally recovered in a flotation circuit at natural or near-natural pulp pH values and with the addition of small amounts of collector.

Recovery of Gold from Gravity Tailings by Flotation

Laboratory scale batch flotation tests were conducted at both natural and elevated pH to investigate the impact of pyrite depression on gold recovery. Results indicated that although an increase in grade from approximately 0.7 g/t to 3 g/t was achievable at a natural pH and a P80 of 134 micron, gold recovery was low at just 35 per cent.
