Pretreatment method for carbon-containing gold ore

The invention belongs to the technical field of carbon-containing gold ore treatment, and particularly relates to a pretreatment method for carbon-containing gold ores, which comprises the following steps: selecting carbonaceous shale and carbonaceous phyllite refractory gold ores, putting the ores into a carbon detection instrument, detecting the carbon content in the ores, if the carbon content is greater than 200g/kg, putting the ores into a reaction kettle, and reacting for 1-2 hours; adding a sodium carbonate solution into the reaction kettle, inflating the reaction kettle after adding the sodium carbonate solution, reacting for 1-5 hours in the reaction kettle, taking out the ore, detecting the carbon content of the taken-out ore again, putting the detected ore into a jaw crusher, and crushing until the particle size of each block is smaller than 100mm; the crushed ore is put into a sodium hypochlorite generator, and then a sodium hypochlorite solution is added into the sodium hypochlorite generator.
