Optimisation of gold recovery by selective gold flotation

Gold flotation is often overlooked as a processing option as the precious metal is viewed as being associated with the sulphide particles present in the ore, even when a proportion of the gold is free. 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

Optimisation of gold recovery by selective gold flotation

01/02/2001· Optimisation of gold recovery by selective gold flotation 231 S-701 was shown to give optimal recovery in an acid float, at an approximate pH of 4.5. S-701 could be used to recover the majority of the pyrite associated gold and then with either xanthate or one of the other new collectors (e.g. F-100) the copper could be recovered at the basic pH. The gold recovery is then maximized to

Flottation Aspects pratiques : Préparation de la pulpe

À l’entrée d’un circuit de flottation, on admet une pulpe minérale qui a subi des opérations de préparation. La première condition pour obtenir une bonne flottation est d’atteindre, par broyage, une libération convenable des particules à flotter, le degré de broyage étant toujours un compromis entre les exigences métallurgiques et économiques.
