Effect of grinding media on the activation of pyrite flotation
The effect of grinding media on pyrite flotation in the presence of collector was tested in the absence of Pb 2+ or Cu 2+. With either mild steel or 30% chromium medium, pyrite displayed very poor flotation. Around 8% recovery was obtained in 8 min of flotation in the presence of collector DBPhos or DTP. It is well known that pyrite displays ...

Galvanic interaction of grinding media with arsenopyrite and pyrite and its effect on gold cyanide leaching
Some electrochemical aspects of grinding media
Cyanide gold leaching was the most efficient when the 30% chromium media was used during the grinding of the ore for both pyrite and arsenopyrite. In addition, in the presence of pyrite, due to the lower galvanic current between pyrite and grinding media in comparison with arsenopyrite, the amount of iron hydroxide was lower, and thus more …
