Since the copper smelting slag contains high content of Fe Cu and valuable metals interest in recycling it is increasing The high Fe content in the copper smelting slag can be used as a high-value element that can replace the foundry pig iron Therefore this study was intended to recover Fe-Cu alloy from the copper smelting slag

Mar 07 2020Copper slag is a by-product created during the copper smelting and refining process As refineries draw metal out of copper ore they produce a large volume of non-metallic dust soot and rock Collectively these materials make up slag which can be used for a surprising number of applications in the building and industrial fields

Some properties of a typical copper slag are shown in Table I and it can be observed that air-cooled copper slag has a black colour and glassy appearance The specific gravity varies with iron content from 2 8 to 3 8 The unit weight of copper slag is somewhat higher than that of conventional aggregate The absorption capacity of the

Granulated copper slag is more porous and therefore has lower specific gravity and higher absorption capacity than air-cooled copper slag The granulated copper slag is made up of regularly shaped angular particles mostly between 4 75 and 0 075 mm (No 200 sieve) in size (Emery 1986 Hughes and Haliburton 1973)
