· kg/t of copper sulphate. 50g/t of sodium ethyl xanthate. kg/t of frother. So, we had to calculate the amounts of reagents we use for this experiment as we were going to use one sample () for froth flotation in a the laboratory flotation cell. Following is how we calculated the amount of copper sulphate equivalent to kg/t.
A wide range of flotation dithiophosphate reagents are produced in acid and aqueous solution froms. MINING Flotation has become a very selective and highly cost efficient process and has become a universally used means for concentrating all types of ores.
The optimum reagent dosages were found to be 12 g/t Z11, 11 g/t AP407, 3 g/t AF65 and 5 g/t AF70 to obtain the maximum copper grade (%). [24] Azizi et al. reported that changing the amount of ...

Flotation Reagent. Flotation reagents have two important structural features: a functional group consisting of donor atoms or ligands, and a substituent group, which is hydrophobic consisting of alkyl aryl hydrocarbon chains in the case of collectors and frothers, or hydrophilic in the case of modifiers (except for inorganic modifiers, which comprise mainly inorganic bases and metal ions).
General guidelines are available for reagent selection in the form of accumulated knowledge base in reagent developer's handbooks and product literature (, Mining Chemicals Handbook). This serves to narrow the selection for a give appliion; however, the metallurgist must still use additional filters to refine the selection to a manageable level to move to the laboratorytesting phase.
