Abstract:The characteristics of temperature increase of minerals and compounds in the microwave field were investigated and the curve of temperature increase was described quantitatively, aimed at exploring newly theoretical foundation for the advanced metallurgical methods of nonferrous metals. The results showed that, temperture increasing rate of many nonferrous metals minerals in microwave field is mainly dependent upon their own characteristics and adsorptivity to microwave. In addition, their temperature increasing rate equations were derived as follows: T =at+b (first stage) and T =(ct+d )1/2 (second stage).
Key words: minerals microwave characteristics of temperature increase
