The zinc concentrate is actually the tails from this bulk separation step. The flotation tailing is the zinc concentrate. If the silver is associated with the galena, the silver reports to the lead concentrate. While pyrite is fairly easy to depress with lime, pyrrhotite is more difficult to depress. An alternative to metabisulphide depression is to aerate the slurry which, if the pyrrhotite is reactive, can render this

Pyrite Depression - Froth Flotation (Sulphide

Pyrite floats at very low pH or gets entrapped during flotation. Column flotation will give good results for such problems. It has forth washing system where entrapped minerals are separated, to get very clean concentrate. 4 years of RD in RDM proved to reduce silica from 7 to 3% in Zinc cleaning in column with very low pyrite.

Pyrite Flotation - Froth Flotation (Sulphide

2. pH is important for pyrite flotation. Normally, pyrite can float well at acid conditions without adding any activator. However, if you want to float the pyrite at alkaline conditions, you need to add Cu2+ as activator, because pyrite can be depressed at alkaline conditions. 3. The effectiveness of activator (e.g. copper sulphate) can be affected by the pulp chemistry, such as pH and Eh. Therefore, it is important
