Ferrokinesis is the ability to summon, control and manipulate all precious metals and jewels. This ability is whilst mostly shown to be possessed by Hades/Pluto and his demigod children. It is also possessed by Gaea (Gaia), the Protogenos of the Earth and if she had any demigod children then they would also possess such an ability.
As the embodiment of the earth, Gaea can bend the metals of her "body" in any shape she wants. Most notably, she was able to create a scythe powerful enough to destroy the body and soul of her fellow primordial consort, Ouranos.
As the god of wealth, Hades can sense and summon any quantity of precious metals and jewels from under the ground, as well as manipulate them. As a result, Hades is known as "The Rich One", and is the richest Olympian. He once offered to build a palace of pure gold for his lover, Maria di Angelo, the mother of Nico di Angelo and the late Bianca di Angelo. While Hades too possesses this ability, it is said to be more relative to his Roman form, Pluto, and as such Pluto's children possess the ability in place of his Greek children.
Children of Pluto
The god of wealth's children also have this ability (though to a much lesser degree), a notable example being Hazel Levesque, who can telekinetically control tons of precious metal simultaneously, as shown when she fought with the Amazons named Lulu and Doris - leaving them buried in a mountain of jewelry - and when she lifted all the gold in the Gryphon's nests. Hazel was also able to detect Nico's sword by sensing the Stygian Iron out of which it was forged.
