Resum
Vitrification of hazardous mine wastes and mine tailings from old mercury and Ag–Pb mines in SE Spain, was studied using solar technology. Six samples were treated in a solar furnace, reaching temperatures of 1050 to 1350 °C. DRX and SEM-EDS microanalysis of the thermally treated samples showed the presence of a dominant vitreous phase with blebs resulting from gas escape, with metals (especially Zn, Cu, Ni) in solid solution. EDX analysis of samples showed the presence of Fe, Ti as well as S...
