The Application of Microwave Energy in Mineral Processing – a Review

Abstract

This paper presents a review of the application of microwave energy in the field of mineral processing at the Institute of Geotechnics,Slovak Academy of Sciences. The influence of microwave radiation of rocks on the failure disintegration of minerals and ores as well as,a modification of magnetic properties and thermal processing of rocks was studied. Moreover, the rate of microwave heating of minerals,effect of microwaves on coal desulphurisation and the extraction of diterpanes from coal were investigated.
