Chapter 14: Flotation of Lead-Zinc Ores Engineering360

The reagent scheme used in the treatment of lead-zinc ores varies considerably and depends on the nature and mineralogy of the ore. In most cases, NaCN-ZnSO 4 depressant system is used with xanthate + dithiophosphate collectors. These reagent schemes are normally employed for treatment of carbonatite and coarse-grained massive sulfides.
