Depressants inhibit the flotation of one mineral or minerals while activators enable the flotation of others. Examples of these include CN −, used to depress all sulfides but galena and this depressant is believed to operate by changing the solubility of chemisorbed and physisorbed collectors on sulfides. This theory originates from Russia.
