The four primary precious metals are gold, silver, platinum, and palladium. Following is a look at what makes a metal precious compared with other metals, plus a list of precious metals. What …
The two metals in the table which are easiest to obtain from their oxide ores are Hg and Ag. Since the Δ Gm ° value for the decomposition of these oxides becomes negative when the temperature is raised, simple heating will cause them to break up into O 2 and the metal. The next easiest metals to obtain are Sn and Fe.

The most abundant varieties in the Earth's crust are aluminum, iron, calcium, sodium, potassium, and magnesium. The vast majority of metals are found in ores (mineral-bearing substances), but a few such as copper, gold, platinum, and silver frequently occur in the free state because they do not readily react with other elements.
