Smelting involves heating up ore until the metal becomes spongy and the chemical compounds in the ore begin to break down. Most important, it releases oxygen from the iron ore, which makes up a high percentage of common iron ores. The most primitive facility used to smelt iron is a bloomery. There, a blacksmith burns charcoal with iron ore and ...Web

The Baraboo District was an active iron mining center in the early 1900s. There were three operational iron mines located in this area by around 1910, shipping naturally concentrated hematitic ore from underground mines. Operation in the Baraboo District ceased by around 1930 and the area no longer contains any known marketable deposits of iron ...Web

This mill pulverized the large chunks of ore that came directly from the mine. Edison planned to process 1200 tons of iron ore every twenty hours. The plant had three magnetic separators that could produce a total of 530 tons of refined ore. There was other equipment to re-refine what was left over to extract even more ore. But technical ...Web
