Iron Ore: From Mining to Processing to Dust Control
Iron ore is a rock or mineral from which metallic iron can be extracted economically. It constitutes 5% of the earth's crust. Viable forms of ore contain between 25% and 60% iron. Ore greater than 60% iron is known as natural ore or direct shipping ore, meaning it can be fed directly into iron-making blast furnaces.

In What Rock Formations Can Gold Be Found? | Sciencing
Alluvium is a deposit of eroded materials and sediment that is gathered into one area. As gold and other materials are eroded, the small pieces are pushed by water and other forces into creek and river beds and other depressions. Because gold is heavier than most other naturally occurring materials, it settles at the bottom of these deposits.
