Solution
\(\text{Sphalerite }- ZnS\)
\(\text{Copper glance }-Cu_{2}S\)
Yes it is possible to separate two sulphide ores by adjusting proportion of oil to water or by using depressants in froth flotation process.
Eg : \(ZnS \)and \(PbS \) can separated by using \(NaCN\).
\(ZnS+4NaCN\to Na_{2}\left [ Zn\left ( CN \right )_{4} \right ]+Na_{2}S\)
\(\text{Copper glance }-Cu_{2}S\)
Yes it is possible to separate two sulphide ores by adjusting proportion of oil to water or by using depressants in froth flotation process.
Eg : \(ZnS \)and \(PbS \) can separated by using \(NaCN\).
\(ZnS+4NaCN\to Na_{2}\left [ Zn\left ( CN \right )_{4} \right ]+Na_{2}S\)
