In mining operations, ore minerals are often separated from valueless minerals by using gravity separation techniques that depend on specific gravity differences. This occurs in natural systems, too. Placer gold deposits form when gold from weathered rock, because of its high specific gravity, concentrates in stream beds. 3.75 Gold nugget on quartz

Cryogenic Air Separation Unit: ... Chrome Ore (FeCr 2 O 4) Also known as chromite, it is a crystalline mineral composed primarily of iron(II) oxide and chromium(III) oxide compounds. The chromium is used to make stainless steel and chrome plating. 199: Pyrochlore Ore ((Na,Ca) 2 Nb 2 O 6 (OH,F))
Pig iron is the raw material for all iron and steel products. This is obtained from chemical reduction of iron ore in a blast furnace by a process called as smelting. The main raw materials required for pig iron are: Iron ore: carbonates, hydrates or oxides of iron; Coking coal: high quality coking coals; Flux, limestone or dolomite.

Although aluminium is a common and widespread element, not all aluminium minerals are economically viable sources of the metal. Almost all metallic aluminium is produced from the ore bauxite (AlO x (OH) 3–2x). Bauxite occurs as a weathering product of low iron and silica bedrock in tropical climatic conditions.
