In a basic oxygen furnace, molten iron ore is the principal raw material and is mixed with varying quantities of steel scrap and alloys to produce different grades of steel. In an electric arc furnace, recycled steel scrap is melted directly into new steel. About 12% of .
Iron ore suppliers follow a process called reduction in which oxygen is removed from iron ores and pure iron is obtained. Iron ore suppliers make use of blast furnaces for the production of steel and other alloys which are used in many industries.
The purpose of a blast furnace is to chemically reduce and physically convert iron oxides into liquid iron called "hot metal". The blast furnace is a huge, steel stack lined with refractory brick, where iron ore, coke and limestone are dumped into the top, and preheated air is blown into the bottom.
Iron ore is converted into various types of iron through several processes. The most common process is the use of a blast furnace to produce pig iron which is about 9294% iron and 35% carbon with smaller amounts of other elements.
A typical ore contains only % to % copper. It is a measure of the value of copper that it is worth extracting it from such small concentrations. The ore is a mixture of minerals and rock (called gangue). The most common copper minerals are:
Ore jennies are a specialized type of hopper car designed exclusively to haul heavy loads of iron ore. The car's history can trace its roots back to the mid1800s although as Mike Schafer notes in his book, "Freight Train Cars," it wasn't until the end of that century when vast veins of ore were ...
