The rule is, only a more reactive element can “steal” an oxygen from an oxide. In this scenario, zinc oxide is reduced by carbon because carbon is more reactive than zinc (refer to the reactivity series). This is why the metal oxides that have metals above carbon on the …

Metal Profile: Iron Properties and Characteristics

Iron was likely originally discovered and extracted as a result of wood burning on top of iron-containing ores. The carbon within the wood would have reacted with the oxygen in the ore, leaving a soft, malleable iron metal. Iron smelting and the use of iron to make tools and weapons began in Mesopotamia (present-day Iraq) between 2700 and 3000 BC.

18.1 Periodicity – Chemistry - opentextbc.ca

Group 2: The Alkaline Earth Metals. The alkaline earth metals (beryllium, magnesium, calcium, strontium, barium, and radium) constitute group 2 of the periodic table. The name alkaline metal comes from the fact that the oxides of the heavier meers of the group react with water to form alkaline solutions.

Magnesium: extraction-Metalpedia

Magnesium: extraction; Brife introduction; Magnesium is found in solution in sea-water (about 1.3 kg m-3 magnesium) and in natural brines. It is also found extensively in the ores magnesite (MgCO3) and dolomite (MgCO3.CaCO3). Both of the two types of resources can be used as raw materials to manufacture magnesium metal.
