Iron and steel emissions.Iron and steel emissions.Iron is believed to be the sixth most abundant element in the universe, and the fourth most abundant on earth.The concentration of iron in the various layers in the structure of the earth ranges from high probably greater than 80, perhaps even a nearly pure iron crystal at the inner core, to only 5 in the outer crust.
March 3, 1999 a metal-making process known to the ancient romans could be pressed into service to bring mars into the iron age - and start opening the solar system to human habitation.If you look at the soil composition of mars, the one thing that really strikes you is that its 5 to 14 percent iron oxide, said dr.Peter curreri, a materials scientist at nasas marshall space flight center.

The more advanced way to smelt iron is in a blast furnace.A blast furnace is charged with iron ore, charcoal or coke coke is charcoal made from coal and limestone caco 3.Huge quantities of air blast in at the bottom of the furnace, and the calcium in the limestone combines with the silicates to form slag.
Aluminum processing - aluminum processing - ores aluminum is the third most abundant element on earths surface.Only oxygen and silicon are more common.Earths crust to a depth of 16 km 10 miles contains 8 percent aluminum.Aluminum has a strong tendency to combine with other common elements and so rarely occurs in nature in the metallic form.
