Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in Iron Oxides and vary in color from dark grey, bright yellow, or deep purple to rusty red. The iron is usually found in the form of Magnetite (Fe3O4, 72.4%Fe) Hematite (Fe2O3, 69.9% Fe), Goethite (FeO(OH), 62.9% Fe), Limonite (FeO(OH)·n(H2O), 55% Fe) or Siderite (FeCO3, 48.2% Fe).

Graphite is a crystalline form of the element Carbon. It consists of stacked layers of Graphene. Graphite occurs naturally and is the most stable form of carbon under standard conditions. Synthetic and Natural Graphite are consumed on large scale (300 kton/Year, in 1989) for uses in pencils, lubricants, and electrodes. Under high pressures and temperatures, it converts to Diamond. It is a weak conductor of heat and electricity.

Lithium is a chemical element with the symbol Li and atomic number 3. It is a soft, silvery-white alkali metal. Under standard conditions, it is the least dense metal and the least dense solid element. Like all alkali metals, Lithium is highly reactive and flammable, and must be stored in vacuum, inert atmosphere, or inert liquid such as purified kerosene or mineral oil. When cut, it exhibits a metallic luster, but moist air corrodes it quickly to a dull silvery gray, then black tarnish. It never occurs freely in nature, but only in (usually ionic) compounds, such as pegmatitic minerals, which were once the main source of Lithium. Due to its solubility as an ion, it is present in ocean water and is commonly obtained from brines. Lithium metal is isolated electrolytically from a mixture of Lithium Chloride and Potassium Chloride.
