Title: SEPARATION OF TIN FROM ALLOYS

Abstract

A process is described for recovering tin from bronze comprising melting the bronze; slowly cooling the melted metal to from 280 to 240 deg C whereby eta- phase bronze crystallizes; separating the eta-bronze crystals from the liquid metal by mechanical means; melting the separated crystals; slowly cooling the melted eta-crystals to a temperature from 520 to 420 deg C whereby crystals of epsilonbronze precipitate; removing said epsilon-crystals from the remaining molten metal; and reintroducing the remaining molten metal into the process for eta-crystallization.
