Effect of Cooling Rate on base Metals Recovery from Copper ...

Rapid cooling of slag by water granulation results in an amorphous and glassy phased slag, encapsulating metal oxides and lowering the solubility of base metals [2, 5, 6 13]. If the slag is cooled too fast, it passes from liquid state to a solid state without developing the crystal structure. Slow cooled slags displays chilled glassy

Fayalite Based Slags: Metal Recovery and Utilization

cooled The main constituents of a copper slag are FeO and SiO 2, each present at about 2055 wt%. The copper content of a smelter slag is normally around 1 wt% while converter slag contains in general much more Cu (2~25 wt%), which is much higher than that of copper ore (~1 wt%), due to overoxidation and entrapment of metal droplets.
