Single Particle Microelectrodes for Electrochemical Analysis of Sulfide Flotation Processes
The true electrochemical characteristics of sulfides found in industrial processes are of interest and as a result a relatively simple technique has been developed to study fundamental electrochemical interactions of individual particles measuring less than 100 microns in diameter. Cyclic voltammetry with sulphide mineral microelectrodes has been carried out on sulphide particles hand-picked from the concentrate and tailings products of an auriferous sulfide ore floated in air and nitrogen. These particles were found to be exclusively pyrite for the +53 micron fraction. Experimental results show no prominent differences in the electrochemical response of these pyrite particles from different flotation products but it appears that particle shape effects can contribute to pyrite losses in the tailings product.
