Sodium Diisobutyl Dithiophosphate is an aqueous solution of dialkyl dithiophosphate. It has practically no frothing characteristics. It is fast and compared to other thiol collectors more selective in the flotation of copper sulphide in the presence of zinc and of iron sulphides and copper activated zinc sulphides from iron sulphides. Other applications are flotation of copper activated iron sulphides, flotation of nickel-bearing minerals, antimony minerals, chalcocite and for improvement in the recovery of precious metals, e. g. gold, silver, platinum. Sodium Diisobutyl Dithiphosphate floats oxide copper minerals as well as sulphide copper in a sulphide-oxide ore very well. This collector has found application in the bulk flotation of copper and cobalt minerals in conjunction with other thiol collectors, usually at neutral PH. It requires only very short conditioning time and is therefore useful for staged addition. It can be used alone or in some cases in combination with an auxiliary collector, such as xan
