The invention belongs to the technical field of wet metallurgy and particularly relates to a method for extracting gold from geyerite through microwaves. The geyerite is subjected to primary microwave treatment, and the microwaves act on substance molecules by means of the specific property of the microwaves, so that molecular motion is accelerated, mutual friction occurs, a lot of heat is generated, reaction is accelerated, the reaction time is greatly shortened, the production efficiency is improved, and the extracting rate of the gold is ensured; during leaching, the microwaves emitted from a microwave reaction kettle are adopted again to enable the material to be continuously subjected to strengthening reaction and decomposition, and thus the leaching rate of the gold is greatly increased; and in addition, the reaction time is further greatly shortened through microwave reaction and shortened from 72 h to 2 h, so that the production efficiency is greatly improved.
