How Do We Separate Two Sulphide Ores By Froth

How Do We Separate Two Sulphide Ores By Froth Floatation Method? For the separation of two sulphide ores, the proportion in which oil and water are taken should be adjusted. This can also be done by using depressants such as NaCN. If an ore contains ZnS and PbS, then NaCN is added during the process. ZnS forms a complex with NaCN preventing it ...

How do we separate two sulphide ores by Froth

Two sulphide ores can be separated by adjusting proportion of oil to water or by using depressants. For example, in the case of an ore containing ZnS and PbS, the depressant NaCN is used.It forms complex with ZnS and prevents it from coming with froth but PbS remains with froth
