WebIn this part of the refinery the four “insoluble” metals – ruthenium, rhodium, iridium and osmium – are extracted and separated as their complex ammonium salts. The final stage in the refining operations – platinum sponge is being melted in a high frequency induction furnace for casting into ingot form.
WebCopper matte contains Cu 2S and FeS. Hot air blast converts FeS to FeO. FeO is removed as slag when it reacts with silica. Hence, copper matte is placed in silica lined converter. 2FeS+O 2→2FeO+2SO 2 FeO+SiO 2→FeSiO 3 Cu 2S or CuO is converted to copper. 2Cu 2S+3O 2→2Cu 2O+2SO 2 2Cu 2O+Cu 2S→6Cu+SO 2 Video Explanation WebIn the Metso Outotec PS Converting Process, the molten matte from the smelting furnace is converted into blister copper. Converting is carried out in two stages. The first stage is the slag blow, where iron contained in the matte is slagged and removed before the copper blow phase. Here, the Metso Outotec Batch Charging System ensures an ...
