Galvanic interaction of grinding media with pyrite and its effect on floatation minerals engineering vol 18 pp 11521163 17 huang g and grano s 2006 galvanic interaction between grinding media and arsenopyrite and its effect on flotation part i quantifying galvanic interaction during grinding international.

Galvanic interactions between different types of grinding media and arsenopyrite and pyrite during the grinding was quantified and the effect of galvanic interactions on gold cyanide leaching was.

Galvanic interactions between sulphide minerals play an important role in flotation interaction between two sulphide minerals or a sulphide mineralgrinding media resulting from their electrochemical relativities is called a galvanic cell the electrochemical reactivity of sulphide minerals is specified by their rest potential.

Grinding media generated more hydrogen peroxide compared to stainless steel media thus lower flotation recovery of galena ground in mild steel could also be attributed due to the presence of higher amounts of h 2o 2 in the pulp liquid besides widely reported galvanic interactions between grinding medium and mineral.

The pulp chemistry properties during the grinding of the goldarsenopyrite or goldpyrite synthetic ores with four different grinding media are given in fig 1as seen in fig 1 the changes from the 30 chromium and ceramic to the forged steel grinding media resulted in a systematic reduction in the pulp potentialthis may be explained by the galvanic interactions between the forged steel.

The electrochemical data were correlated with the amount of the grinding media oxidation during grinding with different media type a linear relationship between the galvanic current and grinding media oxidation was obtained it was found that the higher the galvanic current the higher the amount of iron hydroxide was produced during grinding.

The magotteaux mill system was used to quantify the galvanic interaction between four types of grinding media mild steel 15 chromium 21 chromium and 30 chromium media and arsenopyrite.

The synthetic ores were prepared by mixing arsenopyrite or pyrite with clean gravity gold concentrate and quartz in the presence of arsenopyrite the results showed that when the grinding of the ore was performed using the 30 chromium or ceramic grinding media the gold leaching was more efficient than that when the forged steel media was used based upon the measurement it was suggested that the galvanic interactions between the forged steel grinding media.
