Cyanidation of a pyrrhotite-bearing gold ore

2015-12-27  The Musselwhite Mine plant, originally designed at 3,300tpd, processes a free milling gold orecontaining pyrrhotite as the primary sulphide, at a present throughput of 3,650t/d. The ore is crushed in twostages, using a 1m x 1.4m jaw crusher and 2.1m super heavy-duty cone crusher. The -1.9cm fine ore isground in a conventional rod and ball mill circuit. Gold is recovered by gravity separation prior tocyanidation. Cyanide bearing process water, lime and lead nitrate is added at the rod mill. The grindingthickener underflow is pumped to the cyanidation circuit where cyanide and lime are stage added, asrequired. Oxygen is sparged into leach tanks No. 1 and No. 2, while compressed air is added to theremaining two tanks. The leach slurry flows by gravity to the CIP circuit.
