“…Thus, the concentration of dissolved oxygen will influence the rate of pyrrhotite oxidation [18,20,21,29]. A faster conditioning speed and longer conditioning time increase the amount of dissolved oxygen in the pulp and thus accelerate pyrrhotite oxidization.…”

“…In order to do so, some understanding of the electrochemical reactions active on the surface of pyrrhotite is required. In the electrochemical study of Ekmekci et al (2010) on these particular pyrrhotite samples, three anodic reactions were identified in cyclic voltammetry studies:…”

“…Based on the interpretation that the Gertrude West pyrrhotite (that was 96% liberated) is so reactive that it was already passivated at the time of the oxygen uptake experiment (i.e. that it is even more reactive than the Phoenix pyrrhotite; Ekmekci et al, 2010), there is no conclusive evidence that the reactivity of the Phoenix pyrrhotite was increased due to galvanic effects.…”

“…The solid product of dissociation -pyrrhotized cinder-may be processed by complex methodology resulting in high extraction of iron, sulfur and non-ferrous metals. The technology of processing of pyrrhotized cinders is determined by the content and properties of pyrrhotites formed during decomposition [Novikov 1988, Mianowski 2004, Ekmekci 2010]. M a n u s c r i p t 2 Many options of practical processing have been offered to achieve thermal decomposition of pyrites [Vogan 1981, Craig 1998, Kelner 2004.…”
