Tin anode slime is a by-product of the tin electrolytic refining process. This study investigated a route to separate Sn, Sb, Bi, and Cu from tin anode slime after leaching with hydrochloric acid. In the solvent extraction process with tributyl phosphate, Sb and Sn were extracted into the organic phase. Bi and Cu were unextracted and remained in the liquid phase. In the stripping experiment, Sb and Sn were stripped and separated with HCl and HNO3. Bi and Cu in the aqueous phase were also separated with chemical precipitation procedure by controlling pH value. The purities of Sn, Sb, Cu solution and the Bi-containing solid were 96.25%, 83.65%, 97.51%, and 92.1%. The recovery rates of Sn, Sb, Cu, and Bi were 76.2%, 67.1%, and 96.2% and 92.4%.

Depth Profile Analysis

Comparison of SIMS (top) and GD-MS (bottom) analyses on sample R6-2b (implanted B). dc HR-GD-MS can be used for depth profile analysis of impurities in PV Si with good sensitivity and a depth resolution of 0.5 μm. Concentration profiles of samples contaminated with B, P and Ti agreed well with implanted levels. For fast diffusing transition elements, e.g. Fe and Cu, different impurity distribution mechanisms occur. This should be taken into account when analysing these impurities.
