Flotation Depressants
Sodium cyanide. Sodium cyanide is mainly used to depress sphalerite in the first or lead-flotation stage in separating lead from zinc minerals. Its action on pyrite is nearly as strong as on sphalerite, but it does not affect galena unless a large excess is added or the contact time is too long. The effect of sodium cyanide is often intensified ...

The phase …
Towards tailing grade prediction in zinc flotation via …
In the zinc flotation process, the zinc tailing is discharged at the last scavenger cell, and thus, the tailing grade is expected to be within a desirable range to avoid the waste of valuable minerals (Zhang et al., 2021d). Some plants resort to a single X-ray fluorescence (XRF) analyser to measure the mineral content of multiple flotation ...
