amount of nickel sulphides was lost to the tailings during the nickel flotation. When the nickel flotation feed was sampled and tested in laboratory scale, most of the liberated nickel sulphides were recovered. On the contrary, when the industrial nickel tailing was refloated in laboratory, most of these nickel sulphides were not recovered.

The Froth Flotation Process is about taking advantage of the natural hydrophobicity of liberated (well ground) minerals/metals and making/playing on making them hydrophobic (waterrepel) individually to carefully separate them from one another and the slurry they are in. For this purpose we use chemicals/reagents: Frothers (MIBC) is what allows the formation of air bubbles.

Bulk flotation An efficient procedure for nickel recovery is to combine copper sulphate to activate pentlandite with guar gum to depress talc. This is the method which has been used for the flotation of nickel ores in industry and which we have termed the "standard bulk float". A selection of results for this ore is given in Table 3.
