Metals 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.

In most instances, visible gold can not be seen under microscopic examination of pyrite gold ores. However, if the ore is ground to -200 mesh, most times, a few specs of gold can be visibly seen under microscopic examination.
We need to separate the gold from everything else in the rock so the rock needs to be treated in some way. In New Zealand we chiselled some rocks from an outcrop near a small creek. We were pretty sure our rocks contained some gold as there were disused gold mines dating back from the 1870s close by.

Meteorites that have fallen from space are the only iron found in nature in its pure form. Iron is found naturally in the form of ores that are oxides of the pure metal, such as hematite and magnetite. The most common of the modern methods used to extract iron from its ores is coke smelting in a blast furnace.
