Electrochemistry of Pyrite and its Significance in ...
The concept that the presence of oxygen is essential to the flotation of sulphide minerals is supported by numerous experimental results. Electrochemistry of Pyrite The rest potential of pyrite, corresponding to the open circuit (no net anodic or cathodic current) in 1NHClO4 was observed to be +0.62 volt vs. the standard hydrogen electrode (SHE).

Effect of pyrite type on the electrochemistry of ...
Pyrite is highly floatable and readily enters the flotation concentrates, diluting the grade of valuable products. In addition, it is well known pyrite interacts with other base metal sulphide minerals, such as chalcopyrite. Such interactions are thought to boost pyrite floatability due to copper activation, while
Interfacial Electrochemistry of Pyrite Oxidation and ...
Sodium tetraborate (Na 2 B 4 O 7) has been widely used as an electrolyte and pH buffer in studying the interfacial electrochemistry of sulfide minerals in relation to sulfide mineral flotation.In all the previous studies published so far, borate was regarded as an inert electrolyte/pH buffer, and its reactions with the sulfide minerals were completely overlooked.
Estimating the electrochemical reactivity of pyrite …
As expected, the two pyrite ores showed different impact on Cp flotation. The addition of pyrite to chalcopyrite decreased Cp flotation recovery from 96% to 84% with 50% Py-B and to 74% with 50% Py-A after 10 min of flotation (Fig 14a). This subsequently decreased the Cp grade from 88 to …
