For example, copper smelting waste slag contains Cu 0.2-0.4%, and ferrovanadium smelting waste slag contains V2O50.2-0.3%. ... Referring to recycling the slag, we also can design metal slag recycling plants including lead, iron, steel, nickel, aluminum, copper, and so on according to your actually slag recycling goals.
During the blast furnace process limestone (CaCO 3) flux is added, to collect the waste products produced: silica (SiO 2), phosphorus pentoxide (P 2 O 5), calcium sulfide (CaS), magnesia (MgO) and alumina (Al 2 O 3).This forms blast furnace (BF) slag, which floats on top of the surface of the hot metal (Peters, 1982).The blast furnace is …
The copper smelter slags are highly heterogeneous and chemically diverse (Table 2).The bulk chemical composition of copper slags mainly depends on the metallurgical processes from which they are derived, which are determined by type of concentrate, type of fluxes, type of furnaces and cooling rates (Gbor et al., 2000, 2003; …
Steelmaking plants continuously strive to reduce the environmental load in the steelmaking process, resulting in the recycling of energy, water, and other …
Cement, one of the main components of concrete, poses environmental risks, accounting for 7% of total global carbon emissions. To alleviate the environmental hazards related to cement manufacturing, supplementary cementitious materials (SCM) are employed to reduce the usage of cement in concrete. One SCM used is copper slag …
Fig. 1 shows that the phase diagram of Fe-Cu as well as copper content variation with temperature in Fe-Cu-C system. It indicates that ∼10% copper can be dissolved in the γ-iron phase at 1300 °C/1573 K (Fig. 1 a). Solubility of copper increases with lower carbon content and increasing temperature (Fig. 1 b).Since it is inevitable that …
