How To Extract Iron Ore From The Ground

How Is Iron Extracted From the Earth? | Reference.com

Iron ores in the form of hematite (ferrous oxide) and magnetite are removed from the earth through mining. The use of heavy mining equipment is necessary to dig out large pits in an area with a large deposit of iron ore; however, because iron does not occur naturally, it is necessary to use a blast furnace to separate or refine iron from the other substances in the iron ore.

Extracting Gold | HowStuffWorks

Removing the gold-bearing rock from the ground is just the first step. To isolate pure gold, mining companies use a complex extraction process. The first step in this process is breaking down large chunks of rock into smaller pieces. At a mill, large machines known as crushers reduce the ore to pieces no larger than road gravel. The gravel-like material then enters rotating drums filled with ...

Ways to Separate Metal From Ore | Sciencing

Small, gas-powered smelting furnaces can also be used to separate metal from ore. A cylindrical sheet metal container is built over a gas flame (propane can also be used). Then, a network of tubing is fitted around the smelter. The tubing includes a gas line, an air line, and other piping. A crucible (usually made out of graphite or clay) is used to dip into the smelter to extract molten metal ...
