Molten metals tend to dissolve impurities from the ore. For example, many ores that contain native copper have arsenic compounds associated with them. When the ore is melted, the molten copper dissolves the arsenic. As a result, the metal from the furnace can be less pure than the individual metal grains that were originally in the ground.Web

The first reaction takes place between silicates always containing SiO 2 and iron oxide (= iron ore). It produces an iron-silicate, Fe 2 SiO 4, called fayalite, a major component of pretty much all antique slags.
