How to Separate Gold from Pyrite

Oct 28, 2016 These particles may be separated from the oxides of iron by washing, and the use of nitric acid, followed by panning, is frequently resorted to in order to detect gold in pyrites. Moreover, although usually invisible, gold can sometimes be seen in unroasted pyrites. As long ago as the year 1874, Richard Daintree and Latta found specimens of

Selective flotation of pyrite and gold tellurides

Mar 01, 1997 To overcome the lockup of gold within the roaster, one solution would be to separate the gold tellurides from the roaster feed. Thus, when gold occurs in the form of gold-tellurides with pyrite, which also contains a significant amount of gold, the study of the selective flotation of gold tellurides from pyrite becomes more important.

Flotation of gold and gold-bearing ores ScienceDirect

Jan 01, 2005 Pyrrhotite floats best in acid circuits. The pH range for flotation for gold sulfide ores containing pyrite and arsenopyrite is generally between 7 and 9. Flotation may be carried out at higher pH values of 9 to 10, since this favours the depression of talc minerals and avoids the use of expensive gangue depressants.

Sulphide Flotation an overview ScienceDirect Topics

In the case of mesothermal pyritic gold ores, pyrite and arsenopyrite are sufficiently coarse grained, which allows for good liberation at modest grind fineness (P 80 of 75–120 μm) and results in high-grade concentrates with good recoveries. In some of these ores, submicroscopic gold is exclusively carried by arsenopyrite, which makes separation enticing from the barren pyrite (Donlin Creek
