Extraction auxiliary agent capable of improving gold dissolving speed

The invention discloses an extraction auxiliary agent capable of improving gold dissolving speed. The extraction auxiliary agent comprises the following raw materials of, by weight, 3-8 parts of sodium potassium tartrate, 3-8 parts of ammonium citrate, 2-4 parts of sodium carbonate, 2-3 parts of sodium lignin sulfonate, 1-2 parts of lead salt, and 4-8 parts of sulfonated nitrobenzene; and the usage amount of the auxiliary agent meets the condition that the mass ratio of the auxiliary agent to a gold beneficiation agent is 2-10 to 100-180. According to the auxiliary agent, the gold extraction auxiliary agent is added into the gold beneficiation agent, the gold dissolution speed is obviously increased, the dissolution time is greatly shortened, the production efficiency of gold is improved,the application efficiency of a site is improved, good social benefits, ecological benefits and economic benefits are achieved for the gold industry, and the extraction auxiliary agent is suitable forlarge-scale popularizatio
