Bonjour! je travaille sur un minerai qui contient le cuivre sulfuré mais je fais face à un problème, c'est que mon minerai contient une grande quantité de carbones organiques qui me pousse à faire une pré-flottation et la question est de savoir réactif dois-je utiliser pour flotter le carbo. ...

Un procédé de concentration du minerai de cuivre oxidé comprend la préparation de la pâte, l'introduction dans celle-ci d'un sulfure ionisé, suivi de flottation. Avant de procéder à la flottation, on soumet le sulfure ionisé à l'électrolyse à une densité de courant comprise entre 5 et 500 A/m2. L'on peut utiliser des sulfures contenant de 1 à 9 atomes de soufre.

After the flotation of sulfide lead-zinc minerals, the tailings of the two series merged together into hydro-cyclones for de-sliming, and then the underflow of the hydro-cyclones entered into the zinc oxide ore flotation circuit. Because of de-sliming, the amount of feed ore of zinc oxide ore flotation reduced by nearly half, therefore, the ...

The effect of slime on oxide flotation is strong and the reason is complicated. The feed to the oxide zinc flotation circuit requires careful desliming prior to flotation, which is then performed with a relatively large amount of sulphidizing agent and a cationic collector, with frother added as required (Hosseini and Forssberg, 2006c).
