Electrochemistry of Chalcopyrite Flotation in the Absence and Presence of K-Octyl Hydroxamate

Abstract

This paper reports on electrochemical investigations involving several techniques such as galvanostaiic polarization, cyclic voltammetry and impedance spectroscopy to delermine the effect of oxidation on flotation and wetting behaviour of four different chalcopyrite samples, one from South Africa(obtained through Ward's, New York) and three from India, namely Malanjkhand (fresh), MalanjUhand (tarnished) and Alminrock.
