Refining Gold

When gold is combined in this way, it forms an alloy Scientists and goldsmiths often use colors to designate the various gold alloys that are possible For example, white gold is made by combining gold with nickel, silver or palladium Red or pink gold is an alloy of gold and copper And blue gold is the result of mixing gold with ironMetals with low chemical activity, such a gold and silver are normally found in their pure state Copper, tin, lead, and iron are more reactive and must be heated with carbon to extract the metals Aluminum, calcium, sodium and other active metals are extracted using electrolysis Copper can be extracted from its ores by reduction.
