Galvanic interaction of grinding media with arsenopyrite ...

Grinding media effects on gold – pyrite or gold-arsenopyrite cyanidation was studied. Galvanic interaction between grinding media and sulfide mineral was quantified. The galvanic interaction was highest for forged media and least for 30 chromium. Gold-pyrite extraction was highest due to the lower galvanic interaction.

Effects of grinding media on grinding products and ...

Jan 01 20200183;32;As reported by Song et al. 2007 grinding with ceramic medium is much more beneficial to subsequent pyrite flotation than grinding with iron medium. The improvement in hydrophilicity and low flotation recovery in the case of pyrite ground with iron medium are mainly due to high surface roughness and serious corrosion.
