How to we separate two sulphide ores by Froth Floatation Method? Expla – InterviewSolution

1.	How to we separate two sulphide ores by Froth Floatation Method? Explain with an example.
Answer» Solution :The separation of two sulphide ores can be achieved by adjusting PROPORTION of oil to water or by USING depressants. In the CASE of an ore containing ZNS and PBS, the depressants used in NaCN. It forms complex with ZnS and prevents it from coming with froth but PbS remains with froth.
