What Minerals Form Rocks The list of minerals that commonly form rocks is short With a little practice you will recognize most of them when you see them The Formation of Iron Minerals Downunder Australian The Formation of Iron Most deposits of iron ore in the world are found in rocks known as banded iron formations BIFs In time some oxygen also dissolved in the seawater where it reacted

Mining of banded iron formations involves coarse crushing and screening followed by rough crushing and fine grinding to comminute the ore to the point where the crystallized magnetite and quartz are fine enough that the quartz is left behind when the resultant powder is passed under a magnetic separator

Deep inside Earth between the molten iron core and the thin crust at the surface there is a solid body of rock called the mantle When rock from the mantle melts moves to the surface through the crust and releases pent up gases volcanoes erupt Extremely high temperature and pressure cause the rock to melt and become liquid rock or magma

The body may particularly absorb the binary form of iron Iron is a central component of haemoglobin It binds oxygen and transports it from lungs to other body parts It than transports CO 2 back to the lungs where it can be breathed out Oxygen storage also requires iron Iron is a part of several essential enzymes and is involved in DNA synthesis Normal brain functions are iron dependent

To produce iron they slowly burned iron ore with wood in a clay lined oven The iron separated from the surrounding rock but never quite melted Instead it formed a crusty slag which was removed by hammering This repeated heating and hammering process mixed oxygen with the iron oxide to produce iron and removed the carbon from the metal

Depending on the minerals sandstone can be white yellow pink and almost any color depending on the impurities within the minerals For example red sandstone results from iron oxide in the rock and often causes bands of color Sandstone rocks form in rivers deserts oceans or lakes

Carbon is more reactive than iron so it can push out or displace the iron from iron oxide Here are the equations for the reaction iron oxide carbon → iron carbon dioxide 2Fe 2 O 3 3C → 4Fe 3CO 2 In this reaction the iron oxide is reduced to iron and the carbon is oxidised to carbon dioxide In the blast furnace it is so hot
