  Abstract:  The compounds formed during flotation with oxyne at the surface of smithsonite and blende were studied by IR spectroscopy. By using the potassium bromide pelleting technique the IR spectra were run for blende, smithsonite, oxyne, Zn(II) oxynate, as well as for blende and smithsonite treated with a solution of oxynate. By comparing the obtained spectra the conclusion drawn is that the compound formed at the surface of blende and smithsonite is Zn(II) oxynate.
