The smelting of copper and lead in non-ferrous smelting, for instance, is designed to remove the iron and silica that often occurs with those ores, and separates them as iron-silicate-based slags Slag from steel mills in ferrous smelting, on the other hand, is designed to minimize iron loss and so mainly contains oxides of calcium, silicon .
Some physical and mechanical properties of copper slag is shown in Table 2Air-cooled copper slag has a black colour and glassy appearance The specific gravity varies with iron content, from a low of 28 to as high as 38
materials from copper slag Recovery of copper, molybdenum, precious metals, silica and iron, that is the most abundant component of the slag, are the goals for this research
The copper smelting slag used in this experiment was a slag from a domestic copper smelter, which was generated during smelting and refining by a continuous copper smelting method
88 IRON AND STEEL SLAG (Data in million metric tons unless otherwise noted) Domestic Production and Use: Iron and steel (ferrous) slags are coproducts of iron and steel manufacturing After cooling and processing, ferrous slags are sold primarily to the construction industry
In any copper production plant, more than two tons of slag is discarded with 07–23%Cu to produce each ton of copper Therefore, minimizing copper losses is crucial during the copper matte .
