Metal Losses to the Slag in Smelting and Converting. 80% of the copper produced from ores worldwide originates from sulfide ores. The copper concentrate which results from flotation of the ore is typically smelted and converted to blister copper [].During smelting S and Fe are oxidized, where SiO 2 is added to form a liquid ferric or ferrous silicate slag.
