Abstract
Microwave technology is being increasingly explored in metallurgical processes. The dielectric properties characterize the action mechanism between electromagnetic energy and minerals. Here, a cavity perturbation method was used to survey the dielectric properties of zinc sulfide concentrate with sodium peroxide additive from 20°C to 600°C at 2.45 GHz. The effects of sodium peroxide additives and temperature on the dielectric properties were investigated. Theoretical analyses showed that the zinc sulfide concentration could be heated quickly when the concentration of sodium peroxide was greater than or equal to 6 wt.%. The heating mechanism is mainly Joule heat loss caused by ionic conduction of sodium peroxide. The heating rate comes from energy conversion and heat conduction at temperatures higher than 400°C. Microwave heating experiments and phase formation verified the correctness of the theoretical analyses. The results provide a better understanding of the microwave roasting mechanism of zinc sulfide concentrate, but also support the use of sodium peroxide as a means to promote thermochemical treatments by microwave irradiation.
