Meteor-wrong! It’s Slag!
By Sara Kurth
Have you been doing yard work while stuck at home and found a cool “rock”? Is it heavy, metallic looking and possibly magnetic? Did you just find a meteorite?! Probably not. What you may have found is something called “slag.”
Slag is the by-product of smelting, or the separation of a desired metal out of a raw ore. The most common slag found in the Chicago area is the result of steel production. The creation of steel requires iron. Native iron is rare in nature. Iron ore is derived from iron-rich minerals like hematite and magnetite. Nearly all of the iron ore deposits found on earth are older than 1.8 billion years. At that time, the earth’s oceans were saturated with dissolved iron and virtually no oxygen. Cyanobacteria, the first photosynthetic organisms, began releasing oxygen into the water. The oxygen and dissolved iron interacted, in essence, causing the oceans to rust, forming banded iron formations (BIFs). These BIFs alternate between iron-rich minerals like magnetite and hematite, and iron-poor minerals and shale. These bands are an indication of photosynthetic changes in the environment, thought to be a result of seasons(1).
Fast forward to the age of humans, the use of steel in construction dates back to 1800 B.C. in what is modern day Turkey(2). Prior to the 1850s, the process of making steel was very expensive and reserved only for small, expensive items like armor, swords, and knives. In 1857, Henry Bessemer developed the Bessemer Process, which more efficiently removed impurities from iron ore using oxidation processes(3). This resulted in the ability to mass-produce steel globally. The United States became a world leader in steel production from 1875 through 1970, with steel mills located throughout the country, mainly centered around the Great Lakes region including Pennsylvania, New York, Ohio, Illinois, Indiana, and Michigan. Chicago, ideally located next to Lake Michigan and the I&M canal, and its proximity to the Marquette Iron Range in Michigan, became one of the largest iron and steel producers in the world. By the end of the 19th Century, Chicago steel mills produced a million tons of steel a year(4)!
By the 1970s and ‘80s, however, a steel crisis hit the United States. Nearly a quarter of U.S. steel manufacturing equipment was inefficient, costing more in manhours than the cost for the steel itself. Foreign competition became a contributing factor to the decline in U.S. steel production. Today, the largest steel producer is ArcelorMittal with production facilities located around the world(5).
Although small amounts of steel are still produced in Gary, Indiana, just south of Chicago, the area is no longer the steel production hub of the past. The relics of this age can now be found in your very own backyard! It may not be the coveted meteorite you were hoping for, but slag tells us a story of Chicago’s past and that beauty is truly in the eye of the beholder.
