Processing a Sn–Pb Alloy to Produce Tin

The aim of the work is to develop an optimal method for processing Sn–Pb alloy to obtain a marketable product-branded O1‒O3 tin (Sn ≥ 98.5%). The refining of Sn–Pb alloy composition, %, 53–60 Sn, 18–29 Pb, was carried out, first by vacuum distillation ( T = 1085‒1300°C, P = 15‒100 Рa; τ = 3‒36 h) fo...
