Solution
When there are oxides present in the crude metal as impurities, this technique is used. For example, this process refines crude copper, also referred to as blister copper, that contains cuprous oxide as an impurity. This process involves melting the impure metal on a reverberating furnace’s shallow hearth. The green wood logs are used to stir the molten metal.
