The application of microwave evergy as a substitute for conventional heating has drawn interest from many researchers in extrctive metallurgy. Microwaves have a heating effect just as many other forms of radiant energy. Microwaves the able to penetrate the substance at which they are directed and in being absorbed heat the material from the inside. As a result of heat generated in the interior of a particle, microwaves can affect the rupture of a particle (in this case a host ore) and break down the matrix of the particle (host ore) and expose the recoverable mineral to the leaching reagent.
