The invention discloses a method for microwave-assisted extraction of metal minerals. The method includes the first step of microwave-assisted treatment, the second step of cooling, the third step of ore grinding, the fourth step of separation and the fifth step of metal mineral extraction. The method is simple in step, low in input cost and convenient to achieve, the ore grinding workload is reduced, metal mineral extraction can be simply, conveniently and rapidly completed, efficiency is high, the needed reduction and leaching time is short, the reduction rate and the leaching rate of metal are high, energy conservation and environment friendliness are achieved, the using effect is good, and the problems that in a traditional extraction method, the input cost is large, the operation process is complex, energy consumption is large, the reduction and leaching time are long, and the environment is polluted can be effectively solved.
