impure forms of carbon the extraction of metal from their oxides
Activity Series of Metals: Predicting Reactivity ThoughtCo
Their oxides can be reduced by heating with hydrogen gas, carbon, and carbon monoxide. All the metals from lithium to copper will combine readily with oxygen to form their oxides. The last five metals are found free in nature with little oxides. Their oxides form through alternate pathways and will .

Extraction of Zinc from Zinc Blende Reference Notes
Zinc of higher purity can be obtained by electrolysis. Pure zinc rod is used as cathode while a block of impure zinc is used as anode. A mixture of ZnSO 4 and dill H 2 SO 4 is used as electrolyte. On passing current impure zinc dissolves and equivalent amount of pure zinc is deposited at cathode. Physical Properties . i. It is a blueish white lusticous metal.

Metal Extraction | Iron | Oxide Scribd
THE PROCESS: Molten pig iron is fed into the furnace. Oxygen is blown, under high pressure, through water cooled lances. Nonmetallic impurities are oxidized to gaseous oxides, which escape. Other nongaseous impurities are removed by adding calcium oxide. Measured amounts of carbon and other metals are added to prepare the steel of required quality.

Metal extraction
A metal below carbon in the reactivity series (zinc to silver) may be extracted by heating the metal ore with carbon. During the reaction, the metal in the ore is displaced from its nonmetal anion because carbon is more reactive than the metal.
