  • Rcovery of gold in pyritic ores Mine Engineer.Com

    In most instances visible gold can not be seen under microscopic examination of pyrite gold 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. The incidence of fine gold's quantity

  • Refractory Gold Ore Treatment Methods

    Mispickel in the raw condition in an ore when agitated with strong concentrations of lime or other alkali in the presence of air can yield alkaline arsenites thus (FeAsS)2 + 2Ca(OH) + 130 = 2FeSO4 + 2HCaAsO3 + H2O This reaction is a strong deoxidizer inimical to gold solution by cyanide therefore minimum amounts of lime and cyanide should be employed in order to delay such reaction provided

  • Crusher Reduction Ratio Mineral Processing Metallurgy

    Crusher Reduction Ratio. Therefore if minimum production of fines is desirable it is logical that the heavy end of the 7:1 reduction should be handled in the latter machine. Generally for such a case the split would be about 3:1 to the standard machine and 4:1 to the fine reduction crusher.
