Use of Magnetite as an Ore of Iron. Most of the iron ore mined today is a banded sedimentary rock known as taconite that contains a mixture of magnetite, hematite
First thing to remember about Gold is that it is Heavy, really Heavy. It is 19.3 times heavier then water and about 3 times heavier then iron ( Black Sand ).
Silver (Ag) is generally associated with zinc-lead ore and in gold. In Nepal minor amount of silver is reported in the zinc + lead ore of Ganesh Himal (Rasuwa

But far more important is the use of hematite as an ore of iron. The majority of it is mined from banded iron formations (BIF). These are old (formed generally more
Pyrite is an iron sulfide. Sulfur managed to combine with iron because its strongest competitor oxygen was nowhere to be found. Oxygen was consumed by decomposing
