| Abstract: | The paper considers the studies into the hydrophobic properties of platinum and platinum arsenide, sperrylite, in the solution
with added complexing reagents by using the method of measuring the force of the air bubble abstraction from the mineral surface.
The effect of these complexing reagents on the chemical properties of sperrylite and pyrrhotine is analyzed. A new-developed
procedure for treatment of pyrrhotine by chloroplatinic acid is presented, and the comparative flotation of natural pyrrhotine
and platinum-pretreated pyrrhotine with the complexing reagents is described. The collecting properties of diisobutyl dithiophosphinate
for platinum are determined, and the use of this reagent as an additional collector for platinum-group metals is confirmed
in the course of the experimental flotation of platinum-bearing copper-nickel ore samples.
