Chalcopyrite ores are usually processed by means of hydrometallurgical or pyrometallurgical processes, but due to environmental aspects and the possibility of increased exploitation of mixed and lower grade ores and relatively small isolated deposits, there has been a worldwide upsurge of interest in the hydrometallurgical processes of this ore as compared to pyrometallurgy.
The phosphorus content in LD slag is too high to be reused in iron making and one-hundredth percent of phosphorus go to the metal phase. The major phases present in LD slag in other parts of world are also studied, that contain some reactive mineral phase such as 2CaO.SiO 2, 3CaO.SiO 2, free CaO and MgO (Goldring and Jukes, 1997).
