Abstract

Sposób odzyskiwania ołowiu i metali towarzyszących, zwłaszcza cyny, z ołowiu surowego polega na tym, że proces prowadzi się w trzech fazach obejmujących, w każdej fazie; operacje rafinacji, utleniania, pierwszą i drugą niskoredukcyjne oraz wysokoredukcyjną operację przetapiania. W trzeciej fazie procesu do kotła rafinacyjnego wprowadza się, oprócz ołowiu surowego, stop ołowiowo-cynowy otrzymany po wysokoredukcyjnej operacji przetapiania w drugiej fazie procesu, odpowiednio w proporcjach od 2 : 1 do 10 : 1. Jako reduktor, w operacjach przetapiania, stosuje się węgiel antracytowy. W wysokoredukcyjnych operacjach przetapiania jako topnik dodaje się węglan sodu i związki krzemianowe, odpowiednio w proporcjach od 0,5 : 1 do 2,5 : 1.The method for recovering lead and associated metals, especially tin, from raw lead is that the process is carried out in three phases including each phase; refining, oxidation, first and second low-reduction and high-reduction remelting operations. In the third phase of the process, in addition to raw lead, the lead-tin alloy obtained after the high-reduction remelting operation in the second stage of the process is introduced into the refining boiler, in the proportions from 2: 1 to 10: 1. As a reducer, in remelting operations, coal is used anthracite. In high-reduction remelting operations, sodium carbonate and silicate compounds are added as flux in proportions from 0.5: 1 to 2.5: 1, respectively.
