    These substances are froth stabilizers. For example cresol and aniline. Depressants In the froth floatation process, depressants help in separation of two sulphide ores by prevention of froth formation by one ore and by allowing the other to come into froth. For example, to separate two sulphide ores ZnS and PbS, NaCN is used as a depressant.
