2014-1-1 Slag from copper-smelting operations usually contain between 1.5% and 8% copper depending on process used. After internal recycling, reduction and/or settling, the slag contains between 0.7% and 2% Cu and is often discarded. It is estimated that about 2.2 t of slag is generated per ton of copper produced.

Fig. 2 shows the ternary phase diagram of CaO-SiO 2-Al 2 O 3 system (Levin and McMurdie, 1975).In this figure, the chemical composition of the initial copper slag sample investigated is also shown along with that of a typical Blast Furnace (BF) slag.

Other typical physical properties are given in Table 2.In order to use copper slag as a mineral admixture, it was necessary to carry out an experimental study associating grinding time, average diameter, and pozzolanic activity assessed in mortars [].

The common management options for copper slag are recycling, recovering of metal, production of value added products such as abrasive tools, roofing granules, cutting tools, abrasive, tiles, glass, road-base construction, railroad ballast, asphalt pavements.
Read More2003-11-1 Air-cooled copper slag has a black colour and glassy appearance. The specific gravity varies with iron content, from a low of 2.8 to as high as 3.8. The unit weight of copper slag is somewhat higher than that of conventional aggregate. The absorption capacity of the material is typically very low (0.13%).
