Most gold found in placer deposits is alloyed with small amounts of silver. If the ratio between gold and silver reaches at least 20% silver, the material is called "electrum." Electrum is the name for an alloy of gold and silver. A significant amount of today's silver production is a refining byproduct of gold mining.

A common classification identifies three types of raw materials depending on their extraction process: mined (iron ore, nickel, cobalt, precious metals, etc), plant-based (wood, resins, wheat, corn) or animal-based (milk, meat, etc). Following processing and transformation, they become critical components of a product's primary production.
