Metal compositions and production processes are described. A process for the production of a metal composition includes a first distillation step separating off by evaporation primarily lead from a solder mixture of lead, tin, and antimony, thereby producing as a first concentrated lead stream. The process includes a second distillation step separating primarily lead and antimony from the metal composition, thereby producing a second concentrated lead stream and a second bottom product. The method also includes a third distillation step separating primarily lead and antimony from the second concentrated lead stream, thereby producing a third concentrated lead stream and a third bottom product.

Disclosed is a metal mixture composition containing lead and tin, and comprising by weight at least 10% tin and 45% lead, at least 90% of tin and lead together, more lead than tin, from 1-5000 ppm of copper, at least 0.42% antimony and at least 0.0001 % wt of sulphur, at most 0.1% of the total of chromium, manganese, vanadium, titanium and tungsten, and at most 0.1% of each one of aluminium, nickel, iron and zinc. Disclosed is also a process comprising a pre-treatment step for producing this metal mixture composition, followed by a vacuum distillation step wherein lead is removed by evaporation and a bottom stream is obtained comprising at least 0.6% wt of lead.
