MINTEK | MINTEK

The slags produced during testwork at Mintek were either MgOAl2O3SiO2, shown in Figure 4, or MgOAl2O3SiO2CaO types. The latter slag type is presented in Figure 5 and Figure 6. Fluxing to produce the required slag composition was carried out using either silica or a combination of silica and lime (in the form of burnt lime or limestone).

Copper slag was characterized and processed. The pyrometallurgical processing prospects to generate utilizable materials were arrived at through rigorous thermodynamic analysis. Carbothermal reduction at elevated temperature (near 1440°C) helped recover a majority of the metal values (, Fe, Cu and Mo) into the ironrich alloy product which can be a feed material for steel making.
