Dec 22, 2020 · Froth flotation machine is generally used for the concentration of sulphide ores. The principle behind froth flotation process is that sulphide ores are preferentially wetted by pine oil whereas gangue articles are wetted by water. In this process, the suspension of a powdered ore is made with water. Collectors like pine oil, fatty acids and ...

The process involves a series of flotation known as the differential flotation. In the flotation of copperzinc massive sulfide ores, flotation properties of copper and zinc are determined by the nature and composition of the ore. Copper zinc massive sulfide is even regarded as the most complex ore and consequently the most difficult to treat.
differential froth flotation in lead and zinc ore. Differential froth flotation of sulfide ores EXAMPLE 14 A talcose leadzinc ore containing galena, sphalerite and pyrite was treated with lime and copper sulfate and floated with sodium ethyl xanthate, a solution of thiocarbanilide in dicresyldithiophosphoric acid, and pine oil to give a bulk leadzinc concentrate assaying % Pb, % Zn
In beneficiation of a copper—lead—zinc ore by froth flotation it is often desirable to suppress the flotation of zinc during the initial separation of copper and lead. In this study, it is assumed that this is a desired effect and low values for zinc recovery and Zn:Fe are sought as well as a high recovery and ratios for copper and lead.

Xanthates where also stage added as needed. I did 350 tpd day for 10 years using this differential flotation. Most of the copper and silver in the ore went with the lead concentrate. This ore was very high in pyrite, making a good zinc concentrate difficult.
Lead Zinc Separation by Flotation Froth Flotation. Some of the metals that can do the job are copper and lead At a pH between 89 lead can activate sphalerite to cause it flotation So the reason is during the flotation of the two there may be lead re dissolution from galena which may activate sphalerite to cause it flotation It may best if you are doing bulk flotation of the two
