Mining 101 | Learn How It's Done | Eagle Mine
Eagle Mine in Michigan's Upper Peninsula will produce approximately 440 million pounds of nickel and 429 million pounds of copper. In fact, now in production, Eagle Mine is the only primary nickel mine in the United States and produces 1.5 percent of the world's nickel. So how do we get our ore out from 3,000 feet below the surface?

Corrosion of nanocrystalline and coarse-grained nickel …
Commercially available Nickel 201 (grain size: 45 μm) was used for coarse grained nickel. Coarse-grained Ni-Fe alloys were produced by an arc melting and rolling process at ESPI Metals (Ashland, OR, USA). Coarse-grained materials were ∼3.2 mm in thickness, and had average grain sizes of ∼1000, 960, and 590 μm respectively (Table 1).
