1990-2-1 · The electrochemical nature of mineral-grinding media interaction in the wet grinding of one and two sulfide mineral ores was investigated with regard to the flotation behaviors of the minerals. Two iron sulfides (pyrite and pyrrhotite) and mild steel were used to represent the sulfide minerals and the grinding media, respectively. Galvanic currents in two- and three-electrode combinations

effect of regrinding conditions on the rejection of pyrite

It was found that, after regrinding with mild steel grinding media, the flotation recovery of pyrite is much lower than with stainless steel grinding media, and it is more difficult to …

effect of pyrite and pyrrhotite on the corrosive wear of

A previous investigation showed that corrosion currents estimated from polarization curves for the pyrrhotite - grinding media system under abrasion correlated well with corrosion currents estimated from marked ball wear test data by applying Faraday’s law. Freshly abraded metal debris were magnetically attracted to pyrrhotite and lowered the rest potentials of the mineral particles, thereby

the interaction of grinding media and collector in pyrite

When forged steel was used as the grinding media, a high dosage of MBS was required to depress pyrite, but a low dosage of MBS could almost completely depressed pyrite when high chrome steel

galvanic interaction between chalcopyrite and pyrite with

(ii) Grinding media was anodic relative to pyrite and chalcopyrite, and therefore the electrons flowed from the media to the minerals. Pyrite or chalcopyrite with a higher rest potential acted as the cathode, whilst the grinding media with a lower rest potential acted as the anode, when they were electrochemically contacted in single mineral
