Why copper matte is put in silica lined converter

Why copper matte is put in silica lined converter

 · Copper matte is put in a silica-lined converter to remove the remaining FeO and FeS present in the matte as slag (FeSiO 3). Also, some silica is added to the silica-lined converter. Then, a hot air blast is blown. As a result, the remaining FeS and FeO are converted to iron silicate (FeSiO 3) and Cu 2 S is converted into metallic copper.
