Gold Ore Crusher
As the movable jaw moves towards the fixed jaw, the gold-bearing ore is squeezed between them. This compression action breaks down the larger chunks into smaller pieces that are more suitable for further processing. Imagine this: a chunk of gold-bearing rock is placed into a jaw crusher, and as the jaws close in on it, an immense force is applied.

Iron_ore
Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in colour from dark grey, bright yellow, deep purple, to rusty red. The iron itself is usually found in the form of magnetite (Fe 3 O 4), hematite (Fe 2 O 3), goethite, limonite or siderite.Hematite is also known as "natural ore".

STRENGTH PROPERTIES OF ROCKS AND ROCK MASSES
According to equation (17) the strength ratio Fc/Ft (or Co/To) depends on the value of m only. For limestone m=5.4 and Co/To=5.6; for granite m=29.2 and Co/To=29.2; for sandstone m=14.3 and Co/To=14.3. The Hoek and Brown criterion for intact rock can also be expressed in terms of normal and shear stresses as follows.
Iron Ore Processing, General | SpringerLink
The iron ore processing industry produces usable concentrations of iron-bearing material by removing nonferrous rock (gangue) from low-grade ore. In the United States, predominant iron ore is taconite which is a hard, banded, low-grade ore. Ninety-nine percent of the crude iron ore produced in the United States is taconite.
