heat treatment of iron ore agglomerates with microwave ...

Heat hardening is the most common method employed, mainly in metallurgy. When iron-ore pellets are hardened by oxidizing firing, the ore particles are strengthened by recrystallization, or the gangue constituents fuse while a slag phase develops. The mechanism of hardening is governed by the initial chemical constitution of the input material.
