摘要：

In a technological process of copper production in the flash smelting furnace, slags with high metal contents, such as copper, lead and iron, are generated. These slags differ in their chemical compositions from slags obtained in processes of copper concentrate flash smelting or bath smelting. With the technology used at KGHM, the slag discussed in the article is processed during smelting reduction that is carried out in the electric furnace. As a result, a Cu-Pb-Fe alloy is obtained and subjected to the converting process along with waste slag which contains ca. 0,5 % mass Cu. The article presents an analysis of results of the research on behaviour of iron in the course of slag reduction where diverse fine-grained carbon-bearing materials function as reducers.
