Question

$N a CN$ is sometimes added in the froth floatation process as a depressant when $Z n S$ and $P b S$ minerals are expected because:

Z n S

forms soluble complex

N a_{2} [Z n (CN)_{4}]

while

P b S

form froth

P b (CN)_{2}

is precipitated while no effect on

Z n S

form froth

P b S

forms soluble complex

N a_{2} [Z n (P b)_{4}]

while

Z n S

form froth

N a CN

is never added in froth floatation process

N a CN

is used as a depressant in the separation and concentration of

Z n S

and

P b S

ore. Here,

acts as a depressant for

Z n S

but does not prevent

P b S

from forming the froth.
