  Microwaves have been used for a variety of applications in the past two
decades. However, there has been a significant and growing interest in the
applications of microwaves in hard rock breakage and mineral processing
industries. The purpose of this review paper is to focus on these applications
and to present a careful review of the state-of-the-art experimental and
numerical modeling techniques introduced in the literature from 2000 to 2020.
The challenges involved in this research area are surveyed, and the efforts
that should be made regarding the potential practical implementation of
microwaves in industry are discussed.
