Cyanidation of a pyrrhotitebearing gold ore
The pyrrhotite was found to be 50% hexagonal and 50% monoclinic, using XRD, which is a semiquantitative method The cyanidation tests, performed on finely ground material (89% 37µm), indicated that 978% of the gold is leachable (012g/t Au in the tails; performed in duplicate) The remaining gold is probably locked in sulphide mineralsThe Musselwhite Mine in Canada processes a free milling gold ore at 5558g/t Au and 42% pyrrhotite A laboratory investigation was conducted to improve (PDF) Cyanidation of a pyrrhotitebearing gold oreThe Musselwhite Mine in Canada processes a free milling gold ore at 5558g/t Au and 42% pyrrhotite A laboratory investigation was conducted to improve cyanidation The pyrrhotite was determined to be 50% monoclinic and 50% hexagonal A leach using 8ppm dissolved oxygen yielded only 823% gold extraction with a 029kg/t NaCN consumed The addition of lead [PDF] Cyanidation of a pyrrhotitebearing gold ore
