You work as a chemical engineer, processing metal ores to produce pure metals. You have decided to use a variation on the Hall-Heroult process where the metal ore is melted. After, the molten metal ions are reduced and the metal is plated out of the liquid. Considering that the process of heating is cost prohibitive, and that low melting temperatures are preferred, select which ore for each metal will be best for your process. Iron: Magnetite: Fe_3O_4 Black Iron Sulfide:...
