DEVELOPMENT OF COPPER SLAG PROCESSING TECHNOLOGY BY LOW-
TEMPERATURE REDUCTION

Abstract
:
 The relevance of this work is that for the first time, the task is set to process the slag of 
copper smelters after they are dehumidified to extract iron and its compounds from them. 
Uzbekistan has several iron ore deposits. However, they are not currently involved in industrial 
production. The main reasons are the relatively low content of the main component, relatively 
small reserves, the lack of acceptable processing technology, and problems with engineering 
communications. Slags are an inevitable component of all types of pyrometallurgical methods of 
metal production. In terms of their volumes, they are several times higher than the production 
scale of primary metals. Slags are inherently a waste of production, associated with a decrease 
in the coefficient of integrated use of raw materials and environmental problems. For these 
reasons, the involvement of these fields in industrial production is not expected shortly. At the 
same time, iron-containing raw materials are essential for Uzbeksteel JSC, and this material can 
be extracted from copper slags. In this regard, the relevance of this work is undeniable. The 
problem of processing slags of metallurgical plants is the most acute in both ferrous and 
nonferrous metallurgy. This problem has not been practically solved in any country in the world. 
Slags, accumulating around metallurgical plants, create substantial environmental issues for 
enterprises. The tightening of environmental legislation and the consequent payment of 
significant fines force enterprises to seek alternative solutions.

INTRODUCTION.
The most developed countries bring this production to third states 
and work according to the tolling system. Several countries, such as Finland, have adopted 
legislation under which smelting slags containing no more than 0.60-0.65% of Cu can be sold to 
an external organization and thereby organize wasteless production. 
Such a way of solving the problem of slags is entirely unacceptable for Uzbekistan. We 
have our own economic and social development path based on a careful attitude to natural wealth
