| Research Abstract |
1. The mu tual solubility between the speiss and lead phases is very few in the Pb-Fe-As system. However, the solubility between the two phases increases by the addition of copper in the system. Then, iron speiss is available in the recovery process by metallic lead for valuables.
2. Ag, Au, Bi, Cd, and In are able to recover by metallic lead from the intermediate products and recycling materials
Ga, Co, and Ni are not recovered by metallic lead because the minor elements are distributed in the speiss.
