  • Kinetics And Recovery Of Xanthate Copper Compounds

    Flotation agents are agents used in the mineral flotation process that can adjust the surface properties of minerals and increase or decrease mineral floatability which makes ore pulp properties and foam stability conducive to mineral separation The collector a type of organic substance that can selectively act on the surface of minerals to make the mineral particles hydrophobic The.The reconstructed recovery time curve (combine products) is greater than that of the rougher tailings (scavenger feed) prior to reagent addition By adding collector (BX) in the scavenger feed the ultimate recovery of chalcopyrite increases 20 which means an increase of 1 7 of chalcopyrite recovery in the scavenger feed.

  • Combined Effect Of Operating Parameters On Separation

    Lime is often used in flotation to increase the alkalinity of the pulp An alkaline pH increases the volume of the froth (possibly increasing the rate at which mineral is recovered) and depresses pyrite Frothers such as pine oil and Dowfroth 250 are used to create a froth capable of carrying or.As a result the reagent T 80 is used in flotation in aqueous emulsion or in undissolved form which leads to a relatively large flow rate specified expander So according to data concentrators and conducted flotation experiments used the T 80 at the rate.
