Rcovery of gold in pyritic ores Mine Engineer.Com

The most difficult particles to gravity concentrate are the fines, and 75 microns to 2 microns are definitely very fine. So, even if the ore were ground to 2 microns, it may not be recoverable using current gravity technology. That appears to leave froth flotation as still the best method of recovering the gold from pyritic

Bio-oxidation of Arsenopyritic and Pyritic Containing Gold

Being the most common sulfide minerals, Arsenopyrite and pyrite under oxidizing conditions breaks down to release acids of As and S into the environment, leading to acid mine drainage with high concentrations of dissolved As. In this research, the dissolution of gold ore (with FeS2 and FeAsS as the main sulfides) from Tianli gold mine, Liaoning province, China was investigated.

Sulphide Gold Ore Treatment by Leaching and Flotation Process

Problem with gold recovery from sulphide ore: How may a mill get the maximum recovery of gold from a sulphide ore, at the least capital cost and at the same time obtain the highest net return. This latter point is most important. In many cases a gold mill using an all-cyanide flowsheet with fine grinding of all the ore will report very low gold content in the tailings particularly on an
