Copper Extraction - Wikipedia
Adding silica also reduces the melting point (or, more properly, the liquidus temperature) of the slag, meaning that the smelting process can be operated at a lower temperature. The slag forming reaction is: FeO + SiO 2 → FeO.SiO 2. Slag is less dense than matte, so it forms a layer that floats on top of the matte. ... Read Article
