2.1.1.6.1 FeO–Fe 2 O 3 –SiO 2 Slags. It has been customary since early times in copper smelting, when acid refractories were used universally, to add SiO2 to form a slag with the iron that has been oxidized. This is still the most common practice today, though many furnaces now use basic refractories. Viscosities of slags are important ...

Copper pipes. The chemical properties of copper include the tendency to cause galvanic corrosion. When copper is put in direct contact with certain metals such as iron, corrosion from water can occur to the other metal. The juncture between the metals acts as a battery and produces electrical currents.
