Flotation of Gold and Gold-Bearing Ores ScienceDirect

Jan 01, 2016 Early work on gold particles with copper sulfate showed no improvement in recovery but an increased rate of flotation of gold (Leaver and Woolf, 1934b). More recent laboratory testsing on a refractory gold ore has shown, however, that a 5% increase in free gold flotation recovery is achievable when adding copper sulfate (Teague et al., 1999b).

Modified-three-product column (3PC) flotation of copper

Oct 01, 2011 The flotation of the fresh tailings from the same industrial circuit was also successful in recovering more than 40% of the copper losses and 25% of the gold losses with concentrate grades that were high enough to permit recycling of the recovered copper and gold.

Limits of the CIL circuit in copper–gold plants

Jan 01, 2014 The copper flotation tailings are floated sequentially to produce a gold-bearing pyrite concentrate which is further treated on-site by a CIL process for the recovery of contained gold. Pyrite flotation tailings are discarded to the tailings storage facility without further processing. Copper is simultaneously leached in the CIL process.

Pyrite-gold recovery in copper rougher flotation tailings

The present study investigates the effect of regrinding and aeration on the separation of pyrite from gold in copper rougher flotation tailings (0.07% Cu, 0.61g/t Au, tail grades). An aeration stage was applied both at the head of copper flotation (copper rougher feed) and after regrinding of the copper rougher tailings, before gold/pyrite selective flotation.

Filtration of Copper/Gold Tailings for Mine Backfill BOKELA

Two BoVac Disc filters L176 are operated in a Gold/Copper Mine in Bulgaria for the filtration of flotation tailings which are used for mine backfill. The dewatered and discharged filter cake is mixed with cement and pumped back to the underground to fill the galleries. For this special application the filtered tailings need to have a certain residual moisture to ensure constant conditions for

Tailings.info What Are Tailings? Their nature and production

The five basic types of reagent used in froth flotation recovery include collectors, frothers, depressants, activators and modifiers. When designing the processing plant, the types and quantities of reagents used should be considered together with any depressing requirements to lessen environmental impacts in the tailings streams (Ritcey 1989).
