pyrite with an average Au concentration of 91 ppm was the major carrier of Au in ores McClenaghan et al 2004 According to the data of the LAICPMS analysis Asbearing pyrite of the Brunswick Ore is processed in a complex minerals processing plant The openpit and underground mines supply both course gold and refractory ore to a processing plant that includes crushing grinding gravity recovery flotation oxidation autoclave and Carbon In Pulp CIP circuits to produce a gold dore product and a high grade pyrite concentrate for The goldpyrite association is dependent on ore grade and textural features of the ore When present with pyrite arsenopyrite commonly will have significantly higher gold grades than the pyrite associations Enargite and Luzonite is a common copperarsenic mineral that can be a significant gold carrier

PDF Pyrite Flotation A Review

The ore being sulphide ore is concentrated by froth floatation process Pulverized ore is kept in water containing pine oil and the mixture is agitated by passing compressed air Ore forms froth with pine oil and comes to the surface and is skimmed off while impurities are left in water the processing of complex sulfide ores has focused on the rejection of pyrite and selectivity problem that arises owing to the similar electrochemical behavior of pyrite to the other sulfide Method and apparatus for controlling the flotation process of sulphide ores including separation of sulphide minerals from pyrite in an alkaline environment created by lime The method comprises measuring the molybdenum electrode potential of an aqueous slurry of the ore and adjusting the addition of lime based on the measured molybdenum electrode potential to maintain the molybdenum
