The Mining Industry – Michigan History

Mining in the Marquette Range has decreased significantly since the mid-twentieth century. The Tilden mine and the Empire mine are the only two mines remaining in the Marquette Iron Range. Mining is not of the same importance as it once was in Michigan’s Upper Peninsula, but it still provides important jobs and opportunities in the area.

Iron Ore Mining Techniques Metal Extraction

The iron ore, coke and limestone are crushed into small round pieces and mixed and put on a hopper which controls the input. The most common ores of iron are hematite Fe 2 O 3, and magnetite, Fe 3 O 4. These ores can extract iron by heating them with the carbon present in the coke. Heating coal in the absence of air produces coke.

Particle Analysis in Mining and Minerals

Many of the particles encountered in mining are characterized by sieves (classifiers). Recent advances in computers, cameras, and software make image analysis practical for samples with sizes larger than several microns in diameter. As particle size decreases, sieving and/or dynamic image analysis becomes more arduous or impossible and laser diffraction becomes the technique of choice.
