Abstract

The invention belongs to the technical field of carbon-containing gold ore treatment, and particularly relates to a pretreatment method of carbon-containing gold ores, which comprises the following steps: selecting carbonaceous shale and carbonaceous phyllite type refractory gold ore, putting the ore into a carbon detection instrument, detecting the carbon content in the ore, putting the ore into a reaction kettle if the carbon content is greater than 200g / kg, and reacting for 2-3 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; putting the crushed ore into a sodium hypochlorite generator, and then adding a sodium hypochlorite solution into a sodium hypochlorite generator. According to the pretreatment method for the carbon-containing gold ore, the influence of carbonaceous substances on gold leaching in a cyanide method leaching process of gold can be avoided, and the gold leaching rate is greatly increased.

Description

technical field [0001] The invention relates to the technical field of carbon-containing gold ore processing, in particular to a pretreatment method for carbon-containing gold ore. Background technique [0002] Gold ore refers to ore containing gold elements or gold compounds, which can be processed into gold concentrate or gold ore sand with high gold content after beneficiation. Gold concentrate needs to be refined through smelting. With the large-scale mining of gold mines, the easy-to-handle gold ore resources are gradually exhausted, and the difficult-to-handle gold ore will become the main resource of the gold industry in the future. According to statistics, currently about 2 / 3 of the world's gold resources are refractory ores, and about 1 / 3 of the world's total gold output is produced from refractory gold mines, and this proportion will increase further in the future. In the process of smelting ore, cyanidation method is needed to treat the ore. For carbonaceous shal...
