In this study the removal of sulfur and arsenic from a refractory flotation gold concentrate by microwave heating was investigated. The results showed that cooling pattern of the heated products, heating time, temperature and atmosphere had significant effect on the removal of sulfur and arsenic.
To quantitatively measure and compare the ability of different materials in absorbing microwave energy, a new practical method, only using a home microwave oven with microwave radiation out of the bottom of the cavity as the major apparatus, was developed. During the measuring process, each target material and water, separately contained with two microwave transparent containers, respectively, were...
