cyanidation of a pyrrhotite bearing gold ore

cyanidation process in tin ore advancedGold CIP, CIL System, Heap Leaching, Cyanidation Gold Mine Heap Leaching Process. Crushed by jaw crushers and cone crushers to a certain particle size (30-50mm), raw ore is directly sent for heaping or granulated (to make finer particles agglomerate into coarse powder), and then transported to the ore heap site for heap construction.gold ore cyanidationWhen gold dissolution is complete, the gold-bearing solution is separated from the solids. With ores of higher gold content (greater than 20 grams of gold per tonne of ore), cyanidation is accomplished by vat leaching, which involves holding a slurry of ore and ...Advances in the cyanidation of gold - ScienceDirect1/1/2005· The Musselwhite Mine treats a pyrrhotite-bearing ore containing mostly free gold (5.5–5.8 g/t Au, 4.2% pyrrhotite). The pyrrhotite is both monoclinic (50%) and hexagonal (50%).
