摘      要：More than 40 kinds of selected minerals and compounds were individually irradiated by microwaves under an inert atmosphere,and the temperatures of samples were measured with a metal-sheathed thermocouple inserted into the samples *** results indicated that most sulphide and some oxide minerals and compounds could be heated to high temperatures in a short timet whereas the common gangue minerals,some oxide and oxy-salt minerals or compounds could *** sulphide minerals had faster heating rate than the oxide minerals containing the same *** impurities of minerals had significant effect on the heating *** selective heating characteristics of microwaves on different minerals and compounds could be attributed to the differences between their conductivities or dielectric loss factors and bonding properties.
