A method for generating uniform size-segregated pyrite …

Most samples of the crushed pyrite (~10 g) were milled into a powder using a tungsten carbide mixer mill for approximately 3 minutes. An aliquot of one sample (HY-001) was also ground in an agate mortar and pestle as a comparison to the mixer mill.

Using Pyrite-Rich Cyanide Tailings

The pyrite decomposes into Fe2O3 and SO2, and they react with CaO and Al2O3 to form the intermediates of CaSO4, 2CaOFe2O3, and CaO2Al2O3, which further react to form 3CaO3Al2O3CaSO4, 4CaOAl2O3Fe2O3, and 12CaO7Al2O3. The calcium

Rcovery of gold in pyritic ores

However, if the ore is ground to -200 mesh, most times, a few specs of gold can be visibly seen under microscopic examination. Based upon numerous case studies, it appears that gold particles in pyrite are generally fine, ranging from 75 microns down to 2 or 3 microns.
