Abstract

An ore treating apparatus (10) for subjecting an ore to microwave radiation includes an ore guide or an ore guide component (16) defining a microwave treatment zone having an interior surface at least a portion of which is of a ceramic material, and a microwave guide (12) associated with the microwave treatment zone to guide microwaves emitted from a microwave source into the microwave treatment zone. The invention extends to a method of treating an ore which includes feeding the ore through a microwave treatment zone having a ceramic wall surface, and feeding microwaves into the microwave treatment zone thereby differentially to heat components of the ore.
