According to the difference of material properties (electrical conductivity, magnetic permeability and dielectric constant), the microwave can directly and effectively generate heat in the whole material, and because the microwave can heat most useful minerals but not gangue minerals, obvious local temperature difference can be formed between the useful minerals and the gangue minerals, so that thermal stress is generated between the useful minerals and the gangue minerals, when the thermal stress is large to a certain degree, cracks can be generated on the interfaces between the minerals, and the generation of the cracks can effectively promote monomer dissociation of the useful minerals to separate target metals from the gangue. The microwave radiation (2450 MHz, 1000W) is used to radiate carbon and more than ten kinds of oxides and sulfides, some compounds can be heated to hundreds of ℃ in one minute, and the microwave energy can make atoms and molecules vibrate at high speed, thereby creating more favorable thermodynamic conditions for chemical reactions. Experiments prove that: microwave heating can facilitate extraction of rare metals and heavy metals from ores, processing of industrial waste, and the like. Almost all metals used in industry can be treated with microwaves, with the frequency bands used in industry being 915MHz and 2450 MHz.
