Flotation behaviours of microlite and zircon

In this investigation flotation behaviours of microlite and zircon were studied. Hallimond tube flotation experiments were carried out with pure specimens of microlite and zircon collected from different ore bodies. pH, collector type and depressants were the parameters tested. The results showed that zircon floated in a much better way compared to microlite. Porocoll SAM that is an amphoteric collector was more promising than Porocoll FS-R being a derivate of a fatty acid. Tests indicated that effective separation could be achieved at pH 4. Depressants were observed to deactivate both minerals to some extent.
